Struct vectoreyes::I16x8
source · [−]#[repr(transparent)]pub struct I16x8(_);
Expand description
[i16; 8]
as a vector.
Implementations
sourceimpl I16x8
impl I16x8
sourcepub const fn from_array(array: [i16; 8]) -> I16x8
pub const fn from_array(array: [i16; 8]) -> I16x8
Create a vector from an array.
Unlike the From
trait function, the from_array
function is const
.
Example
const MY_EXTREMELY_FUN_VALUE: I16x8 =
I16x8::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 i16, value);
}
