Struct vectoreyes::U32x8
source · [−]#[repr(transparent)]pub struct U32x8(_);
Expand description
[u32; 8]
as a vector.
Implementations
sourceimpl U32x8
impl U32x8
sourcepub const fn from_array(array: [u32; 8]) -> U32x8
pub const fn from_array(array: [u32; 8]) -> U32x8
Create a vector from an array.
Unlike the From
trait function, the from_array
function is const
.
Example
const MY_EXTREMELY_FUN_VALUE: U32x8 =
U32x8::from_array([0, 1, 2, 3, 4, 5, 6, 7]);
for (i, value) in MY_EXTREMELY_FUN_VALUE.as_array().iter().copied().enumerate() {
assert_eq!(i as u32, value);
}
