Fixed Hash
Provides macros to construct custom fixed-size hash types.
Examples
Simple 256 bit (32 bytes) hash type.
extern crate fixed_hash;
construct_fixed_hash!
Opt-in to add conversions between differently sized hashes.
construct_fixed_hash!
construct_fixed_hash!
// auto-implement conversions between H256 and H160
impl_fixed_hash_conversions!;
// now use the generated conversions
assert_eq!;
assert_eq!;
It is possible to add attributes to your types, for example to make them serializable.
extern crate serde;
extern crate serde_derive;
construct_fixed_hash!
Features
By default this is an standard library depending crate.
For a #[no_std]
environment use it as follows:
fixed-hash = { version = "0.3", default-features = false }
