Mask vector of Mask<i32, N> or Mask<i64, N>.

Provided Associated Constants

const N: usize = N

Number of lanes in this vector.

Required Methods

fn splat(value: bool) -> Self

Constructs a mask by setting all lanes to the given value.

fn from_array(array: [bool; N]) -> Self

Converts an array to a SIMD vector mask.

fn to_array(self) -> [bool; N]

Converts a SIMD vector mask to an array.

fn all(self) -> bool

Returns true if all lanes are set, or false otherwise.

fn any(self) -> bool

Returns true if any lane is set, or false otherwise.

fn set(&mut self, lane: usize, value: bool)

Sets the value of the specified lane.

Panics

Panics if lane is greater than or equal to the number of lanes in the vector.

fn test(&self, lane: usize) -> bool

Tests the value of the specified lane.

Panics

Panics if lane is greater than or equal to the number of lanes in the vector.

Provided Methods

fn len(&self) -> usize

Get the number of lanes in this vector.

fn flag(lane: usize, value: bool) -> Self

Constructs a mask with lane set to value and all the other lanes set to !value.

fn select<S: Select<Self>>(self, true_values: S, false_values: S) -> S

Chooses lanes from two vectors.

For each lane in the mask, choose the corresponding lane from true_values if that lane mask is true, and false_values if that lane mask is false.

fn negate<S: Select<Self> + Neg<Output = S> + Copy>(self, values: S) -> S

Negates lanes if their lane mask is true.

Object Safety

This trait is not object safe.
