Trait KeypairSigner

pub trait KeypairSigner:
    Send
    + Sync
    + Sized
    + Clone {
    // Required methods
    fn account(&self) -> AccountId;
    fn sign(&self, message: &[u8]) -> MultiSignature;
    fn from_string(s: &str, password_override: Option<&str>) -> Result<Self>;

    // Provided method
    fn verify<M: AsRef<[u8]>>(
        &self,
        _sig: &MultiSignature,
        _message: M,
    ) -> Result<bool> { ... }
}

Required Methods

fn account(&self) -> AccountId

fn sign(&self, message: &[u8]) -> MultiSignature

fn from_string(s: &str, password_override: Option<&str>) -> Result<Self>

Provided Methods

fn verify<M: AsRef<[u8]>>( &self, _sig: &MultiSignature, _message: M, ) -> Result<bool>

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.
