sourcepub fn splat(value: bool) -> Mask<T, LANES>
pub fn splat(value: bool) -> Mask<T, LANES>
Construct a mask by setting all lanes to the given value.
sourcepub fn from_array(array: [bool; LANES]) -> Mask<T, LANES>
pub fn from_array(array: [bool; LANES]) -> Mask<T, LANES>

.
Panics
Panics if any lane is not 0 or -1.
sourcepub fn to_int(self) -> Simd<T, LANES>
pub fn to_int(self) -> Simd<T, LANES>
Converts the mask to a vector of integers, where 0 represents false
and -1
represents true

sourcepub unsafe fn test_unchecked(&self, lane: usize) -> bool
pub unsafe fn test_unchecked(&self, lane: usize) -> bool
sourcepub fn test(&self, lane: usize) -> bool
pub fn test(&self, lane: usize) -> bool
