Trait PrehashSigner 

Source 
pub trait PrehashSigner<S> {
    // Required method
    fn sign_prehash(&self, prehash: &[u8]) -> Result<S, Error>;
}
Expand description

Sign the provided message prehash, returning a digital signature.

Required Methods§

Source

fn sign_prehash(&self, prehash: &[u8]) -> Result<S, Error>

Attempt to sign the given message digest, returning a digital signature on success, or an error if something went wrong.

The prehash parameter should be the output of a secure cryptographic hash function.

This API takes a prehash byte slice as there can potentially be many compatible lengths for the message digest for a given concrete signature algorithm.

Allowed lengths are algorithm-dependent and up to a particular implementation to decide.

§Errors

Returns Error in the event prehash is an invalid length.

Dyn Compatibility§

This trait is dyn compatible.

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