Trait SignatureEncoding

pub trait SignatureEncoding:
    Sized
    + Clone
    + for<'a> TryFrom<&'a [u8]>
    + TryInto<Self::Repr> {
    type Repr: 'static + AsRef<[u8]> + Clone + Send + Sync;

    // Provided methods
    fn to_bytes(&self) -> Self::Repr { ... }
    fn to_vec(&self) -> Vec<u8> { ... }
    fn encoded_len(&self) -> usize { ... }
}

Support for decoding/encoding signatures as bytes.

Required Associated Types

type Repr: 'static + AsRef<[u8]> + Clone + Send + Sync

Byte representation of a signature.

Provided Methods

fn to_bytes(&self) -> Self::Repr

Encode signature as its byte representation.

fn to_vec(&self) -> Vec<u8>

Encode signature as a byte vector.

fn encoded_len(&self) -> usize

Get the length of this signature when encoded.

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.

Implementors

impl<C> SignatureEncoding for ecdsa::der::Signature<C>

where C: PrimeCurve, MaxSize<C>: ArrayLength<u8>, <FieldBytesSize<C> as Add>::Output: Add<MaxOverhead> + ArrayLength<u8>,

type Repr = Box<[u8]>

impl<C> SignatureEncoding for ecdsa::Signature<C>

where C: PrimeCurve, SignatureSize<C>: ArrayLength<u8>,

type Repr = GenericArray<u8, <<C as Curve>::FieldBytesSize as Add>::Output>

impl<C> SignatureEncoding for SignatureWithOid<C>

where C: DigestPrimitive, C::Digest: AssociatedOid, SignatureSize<C>: ArrayLength<u8>,

NOTE: this implementation assumes the default digest for the given elliptic curve as defined by hazmat::DigestPrimitive.

When working with alternative digests, you will need to use e.g. SignatureWithOid::new_with_digest.

type Repr = GenericArray<u8, <<C as Curve>::FieldBytesSize as Add>::Output>
