Trait Verifier 

pub trait Verifier<S> {
    // Required method
    fn verify(&self, msg: &[u8], signature: &S) -> Result<(), Error>;
}

Verify the provided message bytestring using Self (e.g. a public key)

Required Methods

fn verify(&self, msg: &[u8], signature: &S) -> Result<(), Error>

Use Self to verify that the provided signature for a given message bytestring is authentic.

Returns Error if it is inauthentic, or otherwise returns ().

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".

Implementations on Foreign Types

impl Verifier<Signature> for SigningKey

fn verify(&self, message: &[u8], signature: &Signature) -> Result<(), Error>
