Struct U16x8

pub struct U16x8(/* private fields */);

[u16; 8] as a vector.

Implementations

impl U16x8

pub const fn from_array(arr: [u16; 8]) -> Self

Create a vector from an array.

Unlike the From trait function, the from_array function is const.

Example

const MY_EXTREMELY_FUN_VALUE: U16x8 = U16x8::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 u16, value);
}
