1//! Provide several simple fixed-sized hash data type and their static constructors.

3//! # Example
4//!
5//! ```rust
6//! use ckb_fixed_hash::{H256, h256};
7//!
8//! const N1: H256 = h256!("0xffffffff_ffffffff_ffffffff_fffffffe_baaedce6_af48a03b_bfd25e8c_d0364141");
9//! const N2: H256 = H256([
10//!     0xff, 0xff, 0xff, 0xff, 0xff, 0xff, 0xff, 0xff, 0xff, 0xff, 0xff, 0xff, 0xff, 0xff, 0xff,
11//!     0xfe, 0xba, 0xae, 0xdc, 0xe6, 0xaf, 0x48, 0xa0, 0x3b, 0xbf, 0xd2, 0x5e, 0x8c, 0xd0, 0x36,
12//!     0x41, 0x41
13//! ]);
14//! assert_eq!(N1, N2);
15//!
16//! const ONE1: H256 = h256!("0x1");
17//! const ONE2: H256 = H256([0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 1]);
