The resulting vectors contain lanes taken alternatively from self and other, first filling the first result, and then the second.

The reverse of this operation is Simd::deinterleave.

let a = Simd::from_array([0, 1, 2, 3]);
let b = Simd::from_array([4, 5, 6, 7]);
let (x, y) = a.interleave(b);
assert_eq!(x.to_array(), [0, 4, 1, 5]);

let a = Simd::from_array([0, 4, 1, 5]);
let b = Simd::from_array([2, 6, 3, 7]);
let (x, y) = a.deinterleave(b);
assert_eq!(x.to_array(), [0, 1, 2, 3]);
assert_eq!(y.to_array(), [4, 5, 6, 7]);

assert_eq!(&dest, &[1, 2, 3, 4, 0, 0]);

pub fn gather_or(slice: &[T], idxs: Simd<usize, N>, or: Self) -> Self

🔬This is a nightly-only experimental API. (portable_simd #86656)

Reads from potentially discontiguous indices in slice to construct a SIMD vector. If an index is out-of-bounds, the element is instead selected from the or vector.

Examples

let vec: Vec<i32> = vec![10, 11, 12, 13, 14, 15, 16, 17, 18];
let idxs = Simd::from_array([9, 3, 0, 5]);  // Note the index that is out-of-bounds
let alt = Simd::from_array([-5, -4, -3, -2]);

let result = Simd::gather_or(&vec, idxs, alt);
assert_eq!(result, Simd::from_array([-5, 13, 10, 15]));

pub fn gather_or_default(slice: &[T], idxs: Simd<usize, N>) -> Selfwhere T: Default,

🔬This is a nightly-only experimental API. (portable_simd #86656)

Reads from indices in slice to construct a SIMD vector. If an index is out-of-bounds, the element is set to the default given by T: Default.

Examples

let vec: Vec<i32> = vec![10, 11, 12, 13, 14, 15, 16, 17, 18];
let idxs = Simd::from_array([9, 3, 0, 5]);  // Note the index that is out-of-bounds

let result = Simd::gather_or_default(&vec, idxs);
assert_eq!(result, Simd::from_array([0, 13, 10, 15]));

pub fn gather_select( slice: &[T], enable: Mask<isize, N>, idxs: Simd<usize, N>, or: Self ) -> Self

🔬This is a nightly-only experimental API. (portable_simd #86656)

Reads from indices in slice to construct a SIMD vector. The mask enables all true indices and disables all false indices. If an index is disabled or is out-of-bounds, the element is selected from the or vector.

Examples

let vec: Vec<i32> = vec![10, 11, 12, 13, 14, 15, 16, 17, 18];
let idxs = Simd::from_array([9, 3, 0, 5]); // Includes an out-of-bounds index
let alt = Simd::from_array([-5, -4, -3, -2]);
let enable = Mask::from_array([true, true, true, false]); // Includes a masked element

let result = Simd::gather_select(&vec, enable, idxs, alt);
assert_eq!(result, Simd::from_array([-5, 13, 10, -2]));

pub unsafe fn gather_select_unchecked( slice: &[T], enable: Mask<isize, N>, idxs: Simd<usize, N>, or: Self ) -> Self

🔬This is a nightly-only experimental API. (portable_simd #86656)

Reads from indices in slice to construct a SIMD vector. The mask enables all true indices and disables all false indices. If an index is disabled, the element is selected from the or vector.

Safety

Calling this function with an enabled out-of-bounds index is undefined behavior even if the resulting value is not used.

Examples

let vec: Vec<i32> = vec![10, 11, 12, 13, 14, 15, 16, 17, 18];
let idxs = Simd::from_array([9, 3, 0, 5]); // Includes an out-of-bounds index
let alt = Simd::from_array([-5, -4, -3, -2]);
let enable = Mask::from_array([true, true, true, false]); // Includes a masked element
// If this mask was used to gather, it would be unsound. Let's fix that.
let enable = enable & idxs.simd_lt(Simd::splat(vec.len()));

// The out-of-bounds index has been masked, so it's safe to gather now.
let result = unsafe { Simd::gather_select_unchecked(&vec, enable, idxs, alt) };
assert_eq!(result, Simd::from_array([-5, 13, 10, -2]));

pub unsafe fn gather_ptr(source: Simd<*const T, N>) -> Selfwhere T: Default,

🔬This is a nightly-only experimental API. (portable_simd #86656)

Read elementwise from pointers into a SIMD vector.

Safety

Each read must satisfy the same conditions as core::ptr::read.

Example

let values = [6, 2, 4, 9];
let offsets = Simd::from_array([1, 0, 0, 3]);
let source = Simd::splat(values.as_ptr()).wrapping_add(offsets);
let gathered = unsafe { Simd::gather_ptr(source) };
assert_eq!(gathered, Simd::from_array([2, 6, 6, 9]));

pub unsafe fn gather_select_ptr( source: Simd<*const T, N>, enable: Mask<isize, N>, or: Self ) -> Self

🔬This is a nightly-only experimental API. (portable_simd #86656)

Conditionally read elementwise from pointers into a SIMD vector. The mask enables all true pointers and disables all false pointers. If a pointer is disabled, the element is selected from the or vector, and no read is performed.

Safety

Enabled elements must satisfy the same conditions as core::ptr::read.

Example

let values = [6, 2, 4, 9];
let enable = Mask::from_array([true, true, false, true]);
let offsets = Simd::from_array([1, 0, 0, 3]);
let source = Simd::splat(values.as_ptr()).wrapping_add(offsets);
let gathered = unsafe { Simd::gather_select_ptr(source, enable, Simd::splat(0)) };
assert_eq!(gathered, Simd::from_array([2, 6, 0, 9]));

pub fn scatter(self, slice: &mut [T], idxs: Simd<usize, N>)

🔬This is a nightly-only experimental API. (portable_simd #86656)

Writes the values in a SIMD vector to potentially discontiguous indices in slice. If an index is out-of-bounds, the write is suppressed without panicking. If two elements in the scattered vector would write to the same index only the last element is guaranteed to actually be written.

Examples

let mut vec: Vec<i32> = vec![10, 11, 12, 13, 14, 15, 16, 17, 18];
let idxs = Simd::from_array([9, 3, 0, 0]); // Note the duplicate index.
let vals = Simd::from_array([-27, 82, -41, 124]);

vals.scatter(&mut vec, idxs); // two logical writes means the last wins.
assert_eq!(vec, vec![124, 11, 12, 82, 14, 15, 16, 17, 18]);

pub fn scatter_select( self, slice: &mut [T], enable: Mask<isize, N>, idxs: Simd<usize, N> )

🔬This is a nightly-only experimental API. (portable_simd #86656)

Writes values from a SIMD vector to multiple potentially discontiguous indices in slice. The mask enables all true indices and disables all false indices. If an enabled index is out-of-bounds, the write is suppressed without panicking. If two enabled elements in the scattered vector would write to the same index, only the last element is guaranteed to actually be written.

Examples

let mut vec: Vec<i32> = vec![10, 11, 12, 13, 14, 15, 16, 17, 18];
let idxs = Simd::from_array([9, 3, 0, 0]); // Includes an out-of-bounds index
let vals = Simd::from_array([-27, 82, -41, 124]);
let enable = Mask::from_array([true, true, true, false]); // Includes a masked element

vals.scatter_select(&mut vec, enable, idxs); // The last write is masked, thus omitted.
assert_eq!(vec, vec![-41, 11, 12, 82, 14, 15, 16, 17, 18]);

pub unsafe fn scatter_select_unchecked( self, slice: &mut [T], enable: Mask<isize, N>, idxs: Simd<usize, N> )

🔬This is a nightly-only experimental API. (portable_simd #86656)

Writes values from a SIMD vector to multiple potentially discontiguous indices in slice. The mask enables all true indices and disables all false indices. If two enabled elements in the scattered vector would write to the same index, only the last element is guaranteed to actually be written.

Safety

Calling this function with an enabled out-of-bounds index is undefined behavior, and may lead to memory corruption.

Examples

let mut vec: Vec<i32> = vec![10, 11, 12, 13, 14, 15, 16, 17, 18];
let idxs = Simd::from_array([9, 3, 0, 0]);
let vals = Simd::from_array([-27, 82, -41, 124]);
let enable = Mask::from_array([true, true, true, false]); // Masks the final index
// If this mask was used to scatter, it would be unsound. Let's fix that.
let enable = enable & idxs.simd_lt(Simd::splat(vec.len()));

// We have masked the OOB index, so it's safe to scatter now.
unsafe { vals.scatter_select_unchecked(&mut vec, enable, idxs); }
// The second write to index 0 was masked, thus omitted.
assert_eq!(vec, vec![-41, 11, 12, 82, 14, 15, 16, 17, 18]);

pub unsafe fn scatter_ptr(self, dest: Simd<*mut T, N>)

🔬This is a nightly-only experimental API. (portable_simd #86656)

Write pointers elementwise into a SIMD vector.

Safety

Each write must satisfy the same conditions as core::ptr::write.

Example

let mut values = [0; 4];
let offset = Simd::from_array([3, 2, 1, 0]);
let ptrs = Simd::splat(values.as_mut_ptr()).wrapping_add(offset);
unsafe { Simd::from_array([6, 3, 5, 7]).scatter_ptr(ptrs); }
assert_eq!(values, [7, 5, 3, 6]);

pub unsafe fn scatter_select_ptr( self, dest: Simd<*mut T, N>, enable: Mask<isize, N> )

🔬This is a nightly-only experimental API. (portable_simd #86656)

Conditionally write pointers elementwise into a SIMD vector. The mask enables all true pointers and disables all false pointers. If a pointer is disabled, the write to its pointee is skipped.

Safety

Enabled pointers must satisfy the same conditions as core::ptr::write.

Example

let mut values = [0; 4];
let offset = Simd::from_array([3, 2, 1, 0]);
let ptrs = Simd::splat(values.as_mut_ptr()).wrapping_add(offset);
let enable = Mask::from_array([true, true, false, false]);
unsafe { Simd::from_array([6, 3, 5, 7]).scatter_select_ptr(ptrs, enable); }
assert_eq!(values, [0, 0, 3, 6]);
