Trait EcPk

pub trait EcPk:
    Clone
    + Eq
    + Send
    + Debug
    + MultiDisplay<Encoding> {
    type Compressed: Copy + Sized + Send + AsRef<[u8]>;

    // Required methods
    fn base_point() -> Self;
    fn to_pk_compressed(&self) -> Self::Compressed;

}

Elliptic-curve based public key type which can be used in ECDH or signature schemes.

Safety

The type provides no guarantees on the key validity upon deserialization.

Required Associated Constants

const COMPRESSED_LEN: usize

const CURVE_NAME: &'static str

Required Associated Types

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

Required Methods

fn base_point() -> Self

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

fn from_pk_compressed(pk: Self::Compressed) -> Result<Self, EcPkInvalid>

fn from_pk_compressed_slice(slice: &[u8]) -> Result<Self, EcPkInvalid>

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.
