pub struct I8x16(_);

Expand description

[i8; 16] as a vector.

Implementations

source

impl I8x16

source

pub const fn from_array(array: [i8 ; 16]) -> I8x16

Create a vector from an array.

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

Example

const MY_EXTREMELY_FUN_VALUE: I8x16 =
    I8x16::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 i8, value);
}
