Trait tendermint::signature::Verifier[−][src]

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

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

Required methods

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

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

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