Marker trait for elliptic-curve based signatures

Required Associated Constants

const COMPRESSED_LEN: usize

Required Associated Types

type Pk: EcPk

type Compressed: Copy + Sized + Send + AsRef<[u8]>

Required Methods

fn to_sig_compressed(&self) -> Self::Compressed

fn from_sig_compressed(sig: Self::Compressed) -> Result<Self, EcSigInvalid>

fn from_sig_compressed_slice(slice: &[u8]) -> Result<Self, EcSigInvalid>

fn verify( &self, pk: &Self::Pk, msg: impl AsRef<[u8]>, ) -> Result<(), EcVerifyError>

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
