Trait sp_core::crypto::ByteArray

pub trait ByteArray: AsRef<[u8]> + AsMut<[u8]> + for<'a> TryFrom<&'a [u8], Error = ()> {
    const LEN: usize;

    // Provided methods
    fn from_slice(data: &[u8]) -> Result<Self, ()> { ... }
    fn to_raw_vec(&self) -> Vec<u8>  { ... }
    fn as_slice(&self) -> &[u8]  { ... }
}

Trait used for types that are really just a fixed-length array.

Required Associated Constants

const LEN: usize

The “length” of the values of this type, which is always the same.

Provided Methods

fn from_slice(data: &[u8]) -> Result<Self, ()>

A new instance from the given slice that should be Self::LEN bytes long.

fn to_raw_vec(&self) -> Vec<u8>

Return a Vec<u8> filled with raw data.

fn as_slice(&self) -> &[u8]

Return a slice filled with raw data.

Object Safety

This trait is not object safe.
