#[repr(transparent)]
pub struct U8x32(_);

Expand description

[u8; 32] as a vector.

Implementations

source

impl U8x32

source

pub const fn from_array(array: [u8 ; 32]) -> U8x32

Create a vector from an array.

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

Example

const MY_EXTREMELY_FUN_VALUE: U8x32 =
    U8x32::from_array([0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31]);
for (i, value) in MY_EXTREMELY_FUN_VALUE.as_array().iter().copied().enumerate() {
    assert_eq!(i as u8, value);
}
