ootle_byte_type

Lightweight conversion traits between rich types and their flat fixed byte-array representations. Useful for serialisation boundaries where allocating or expensive Edwards point decompression operations are undesirable.

Traits

Trait	Direction	Method
`ToByteType`	`T → Bytes`	`to_byte_type(&self) -> Self::ByteType`
`ConvertFromByteType<B>`	`Bytes → T`	`convert_from_byte_type(bytes: &B) -> Result<Self, _>`
`FromByteType<T>`	`Bytes → T` (blanket)	`try_from_byte_type(&self) -> Result<T, _>`

FromByteType is automatically implemented for any B where T: ConvertFromByteType<B>, so you only need to implement ConvertFromByteType.

Example

use ootle_byte_type::{ToByteType, FromByteType};
use tari_crypto::{keys::PublicKey, ristretto::RistrettoPublicKey};
use tari_template_lib_types::crypto::RistrettoPublicKeyBytes;

// Rich type → bytes
let (_, pk) = RistrettoPublicKey::random_keypair( & mut rand::thread_rng());
let bytes: RistrettoPublicKeyBytes = pk.to_byte_type();

// Bytes → rich type
let pk2: RistrettoPublicKey = bytes.try_from_byte_type().unwrap();
assert_eq!(pk, pk2);

With the crypto feature (enabled by default) implementations are provided for RistrettoPublicKey, PedersenCommitment, SchnorrSignature, CommitmentSignature, and Option<T>.
