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

Operations on SIMD vectors of mutable pointers.

Required Associated Types

type Usize

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

Vector of usize with the same number of lanes.

type Isize

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

Vector of isize with the same number of lanes.

type ConstPtr

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

Vector of constant pointers to the same type.

type Mask

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

Mask type used for manipulating this SIMD vector type.

Required Methods

fn is_null(self) -> Self::Mask

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

Returns true for each lane that is null.

fn cast_const(self) -> Self::ConstPtr

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

Changes constness without changing the type.

Equivalent to calling pointer::cast_const on each lane.

fn addr(self) -> Self::Usize

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

Gets the “address” portion of the pointer.

This method discards pointer semantic metadata, so the result cannot be directly cast into a valid pointer.

Equivalent to calling pointer::addr on each lane.

fn with_addr(self, addr: Self::Usize) -> Self

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

Creates a new pointer with the given address.

This performs the same operation as a cast, but copies the address-space and provenance of self to the new pointer.

Equivalent to calling pointer::with_addr on each lane.

fn expose_addr(self) -> Self::Usize

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

Gets the “address” portion of the pointer, and “exposes” the provenance part for future use in Self::from_exposed_addr.

fn from_exposed_addr(addr: Self::Usize) -> Self

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

Convert an address back to a pointer, picking up a previously “exposed” provenance.

Equivalent to calling core::ptr::from_exposed_addr_mut on each lane.

fn wrapping_offset(self, offset: Self::Isize) -> Self

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

Calculates the offset from a pointer using wrapping arithmetic.

Equivalent to calling pointer::wrapping_offset on each lane.

fn wrapping_add(self, count: Self::Usize) -> Self

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

Calculates the offset from a pointer using wrapping arithmetic.

Equivalent to calling pointer::wrapping_add on each lane.

fn wrapping_sub(self, count: Self::Usize) -> Self

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

Calculates the offset from a pointer using wrapping arithmetic.

Equivalent to calling pointer::wrapping_sub on each lane.
