Enum std::simd::Which

pub enum Which {
    First(usize),
    Second(usize),
}

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

Specifies a lane index into one of two SIMD vectors.

This is an input type for Swizzle2 and helper macros like simd_swizzle.

Variants

First(usize)

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

Index of a lane in the first input SIMD vector.

Second(usize)

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

Index of a lane in the second input SIMD vector.

Trait Implementations

impl Clone for Which

fn clone(&self) -> Which

Returns a copy of the value.

const fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Which

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl Hash for Which

fn hash<__H>(&self, state: &mut __H)where
    __H: Hasher,

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)where
    H: Hasher,

Feeds a slice of this type into the given Hasher.

impl Ord for Which

fn cmp(&self, other: &Which) -> Ordering

This method returns an Ordering between self and other.

const fn max(self, other: Self) -> Self

Compares and returns the maximum of two values.

const fn min(self, other: Self) -> Self

Compares and returns the minimum of two values.

const fn clamp(self, min: Self, max: Self) -> Selfwhere
    Self: PartialOrd<Self>,

Restrict a value to a certain interval.

impl PartialEq<Which> for Which

fn eq(&self, other: &Which) -> bool

This method tests for self and other values to be equal, and is used by ==.

const fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl PartialOrd<Which> for Which

fn partial_cmp(&self, other: &Which) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

const fn lt(&self, other: &Rhs) -> bool

This method tests less than (for self and other) and is used by the < operator.

const fn le(&self, other: &Rhs) -> bool

This method tests less than or equal to (for self and other) and is used by the <= operator.

const fn gt(&self, other: &Rhs) -> bool

This method tests greater than (for self and other) and is used by the > operator.

const fn ge(&self, other: &Rhs) -> bool

This method tests greater than or equal to (for self and other) and is used by the >= operator.
