Struct U16x16

pub struct U16x16(/* private fields */);

[u16; 16] as a vector.

Implementations

impl U16x16

pub const fn from_array(arr: [u16; 16]) -> Self

Create a vector from an array.

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

Example

const MY_EXTREMELY_FUN_VALUE: U16x16 = U16x16::from_array([
    0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15,
]);
for (i, value) in MY_EXTREMELY_FUN_VALUE.as_array().iter().copied().enumerate() {
    assert_eq!(i as u16, value);
}
