Struct na::simd::SimdOption
source · [−]pub struct SimdOption<V> where
V: SimdValue, { /* private fields */ }Expand description
Generalization of Option for SIMD computation.
Implementations
sourceimpl<V> SimdOption<V> where
V: SimdValue,
impl<V> SimdOption<V> where
V: SimdValue,
sourcepub fn new(val: V, mask: <V as SimdValue>::SimdBool) -> SimdOption<V>
pub fn new(val: V, mask: <V as SimdValue>::SimdBool) -> SimdOption<V>
Creates a new SIMD option by combining a value and a mask indicating what lane of the value is valid.
sourcepub fn option(self) -> Option<V>
pub fn option(self) -> Option<V>
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.
sourcepub fn simd_unwrap(self) -> V
pub fn simd_unwrap(self) -> V
Retrieve the underlying value if all the bits of self.mask are 1.
Panics if any of the bits of self.mask is 0.
sourcepub fn simd_unwrap_or(self, other: impl FnOnce() -> V) -> V
pub fn simd_unwrap_or(self, other: impl FnOnce() -> V) -> V
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.

superset. Read more
sourcefn is_in_subset(&self) -> bool
fn is_in_subset(&self) -> bool
Checks if self is actually part of its subset T (and can be converted to it).

The inclusion map: converts self to the equivalent element of its superset.
