Trait signature::Signature

pub trait Signature: AsRef<[u8]> + Debug + Sized {
    fn from_bytes(bytes: &[u8]) -> Result<Self, Error>;

    fn as_bytes(&self) -> &[u8] { ... }
}

Trait impl'd by concrete types that represent digital signatures.

Signature types must (as mandated by the AsRef<[u8]> bound) be a thin wrapper around the "bag-of-bytes" serialized form of a signature which can be directly parsed from or written to the "wire".

For signature systems which require a more advanced internal representation (e.g. involving decoded scalars or decompressed elliptic curve points) it's recommended that "provider" libraries maintain their own internal signature type and use From bounds to provide automatic conversions.
