Struct fuel_types::Bytes4

pub struct Bytes4(_);

FuelVM atomic type.

Implementations

impl Bytes4

pub const LEN: usize

Memory length of the type

pub const fn new(bytes: [u8; 4]) -> Self

Bytes constructor.

pub const fn zeroed() -> Bytes4

Zeroes bytes constructor.

pub unsafe fn from_slice_unchecked(bytes: &[u8]) -> Self

Add a conversion from arbitrary slices into owned

Warning

This function will not panic if the length of the slice is smaller than Self::LEN. Instead, it will cause undefined behavior and read random disowned bytes

pub unsafe fn as_ref_unchecked(bytes: &[u8]) -> &Self

Copy-free reference cast
