doughnut-rs
Rust implementation of the doughnut binary codec.
Currently compliant with version 0, 1 spec.
use doughnut_rs::v1::DoughnutV1;
let encoded_doughnut = vec![ <some bytes> ];
let doughnut = DoughnutV1::new(&encoded_doughnut)?;
Query permission topping
let topping: &[u8] = doughnut.get_topping("something")?;
Check a doughnut is valid to be used by a user (who
) at a timestamp (when
).
use doughnut_rs::traits::DoughnutApi;
// ..
assert!(
doughnut.validate(who, when).is_ok()
)
Verify a doughnut's signature (requires "crypto"
feature in "no_std"
mode and rust nightly)
use doughnut_rs::traits::DoughnutVerify;
// ..
assert!(doughnut.verify().is_ok());
Sign a doughnut (requires "crypto"
feature in "no_std"
mode and rust nightly)
use doughnut_rs::traits::Signing;
let mut doughnut = DoughnutV1 { ... };
// ECDSA
assert!(doughnut.sign_ecdsa(<secret_key_bytes>).is_ok());
// EIP191
assert!(doughnut.sign_eip191(<secret_key_bytes>).is_ok());
