Implementations

`impl f32x8`[src]

`pub const fn new( x0: f32, x1: f32, x2: f32, x3: f32, x4: f32, x5: f32, x6: f32, x7: f32 ) -> Self`[src]

Creates a new instance with each vector elements initialized with the provided values.

`pub const fn lanes() -> usize`[src]

Returns the number of vector lanes.

`pub const fn splat(value: f32) -> Self`[src]

Constructs a new instance with each element initialized to value.

`pub fn extract(self, index: usize) -> f32`[src]

Extracts the value at index.

Panics

If index >= Self::lanes().

`pub unsafe fn extract_unchecked(self, index: usize) -> f32`[src]

Extracts the value at index.

Safety

If index >= Self::lanes() the behavior is undefined.

#[must_use = "replace does not modify the original value - \ it returns a new vector with the value at `index` \ replaced by `new_value`d"] pub fn replace(self, index: usize, new_value: f32) -> Self [src]

Returns a new vector where the value at index is replaced by new_value.

Panics

If index >= Self::lanes().

#[must_use = "replace_unchecked does not modify the original value - \ it returns a new vector with the value at `index` \ replaced by `new_value`d"] pub unsafe fn replace_unchecked(self, index: usize, new_value: f32) -> Self [src]

Returns a new vector where the value at index is replaced by new_value.

Safety

If index >= Self::lanes() the behavior is undefined.

`impl f32x8`[src]

`pub fn min(self, x: Self) -> Self`[src]

Minimum of two vectors.

Returns a new vector containing the minimum value of each of the input vector lanes.

`pub fn max(self, x: Self) -> Self`[src]

Maximum of two vectors.

Returns a new vector containing the maximum value of each of the input vector lanes.

`impl f32x8`[src]

`pub fn sum(self) -> f32`[src]

Horizontal sum of the vector elements.

The intrinsic performs a tree-reduction of the vector elements. That is, for an 8 element vector:

((x0 + x1) + (x2 + x3)) + ((x4 + x5) + (x6 + x7))

If one of the vector element is NaN the reduction returns NaN. The resulting NaN is not required to be equal to any of the NaNs in the vector.

`pub fn product(self) -> f32`[src]

Horizontal product of the vector elements.

The intrinsic performs a tree-reduction of the vector elements. That is, for an 8 element vector:

((x0 * x1) * (x2 * x3)) * ((x4 * x5) * (x6 * x7))

If one of the vector element is NaN the reduction returns NaN. The resulting NaN is not required to be equal to any of the NaNs in the vector.

`impl f32x8`[src]

`pub fn max_element(self) -> f32`[src]

Panics
