Trait Implementations

Performs copy-assignment from source.

impl Debug for Signature

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<D> DigestVerifier<D, Signature> for VerifyingKey<D>

where D: Digest + FixedOutputReset + Update,

fn verify_digest<F: Fn(&mut D) -> Result<()>>( &self, f: F, signature: &Signature, ) -> Result<()>

impl Display for Signature

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

fn from(signature: Signature) -> Box<[u8]>

impl PartialEq for Signature

fn eq(&self, other: &Signature) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
