Struct na::simd::SimdOption [−][src]
pub struct SimdOption<V> where
V: SimdValue, { /* fields omitted */ }
Generalization of Option for SIMD computation.
Implementations
impl<V> SimdOption<V> where
V: SimdValue,
[src]
impl<V> SimdOption<V> where
V: SimdValue,
[src]pub fn new(val: V, mask: <V as SimdValue>::SimdBool) -> SimdOption<V>
[src]
Creates a new SIMD option by combining a value and a mask indicating what lane of the value is valid.
pub fn mask(&self) -> <V as SimdValue>::SimdBool
[src]
Return the underlying SIMD boolean mask.
pub fn value(&self) -> &V
[src]
Return the underlying unfiltered value.
pub fn option(self) -> Option<V>
[src]
Converts this SIMD option to a strandard Option.
If all the bits of self.mask
are 1, then this returns Some(self.value())
.
If any bit of self.mask
is 0, then this returns None
.
pub fn simd_unwrap(self) -> V
[src]
Retrieve the underlying value if all the bits of self.mask
are 1.
Panics if any of the bits of self.mask
is 0.
pub fn simd_unwrap_or(self, other: impl FnOnce() -> V) -> V
[src]
Merges the value of self
with the value of other
.
Each lane of the result with a corresponding bit mask set to 1 will be filled with the corresponding lanes of self.value()
.
The lanes of the result with a corresponding bit mask set to 0 will be filled with the corresponding lanes of other()
.
The function in other
should not do any side-effect. Indeed, implementors of this trait are free to decide in what
cases other
is called or not.
