Wrap a fixed-size byte array in a newtype, delegating all methods to the underlying crate::FixedBytes.

This functionally creates a new named FixedBytes that cannot be type-confused for another named FixedBytes.

Examples

use alloy_primitives::wrap_fixed_bytes;

// These hashes are the same length, and have the same functionality, but
// are distinct types
wrap_fixed_bytes!(pub struct KeccakOutput<32>;);
wrap_fixed_bytes!(pub struct MerkleTreeItem<32>;);
