Trait FixedBytesVecExt

pub trait FixedBytesVecExt {
    // Required method
    fn into_flattened(self) -> Vec<u8> ⓘ;
}

Expand description

Extension trait for flattening a Vec of FixedBytes to a Vec<u8>.

This mirrors the standard library’s into_flattened method for Vec<[T; N]>.

Required Methods§

fn into_flattened(self) -> Vec<u8> ⓘ

Takes a Vec<FixedBytes<N>> and flattens it into a Vec<u8>.

§Panics

This panics if the length of the resulting vector would overflow a usize.

This is only possible when N == 0, which tends to be irrelevant in practice.

§Examples

use alloy_primitives::{FixedBytes, FixedBytesVecExt};

let mut vec = vec![
    FixedBytes::<4>::new([1, 2, 3, 4]),
    FixedBytes::new([5, 6, 7, 8]),
    FixedBytes::new([9, 10, 11, 12]),
];
assert_eq!(vec.pop(), Some(FixedBytes::new([9, 10, 11, 12])));

let mut flattened = vec.into_flattened();
assert_eq!(flattened.pop(), Some(8));
