Trait Signer 

pub trait Signer {
    type Signature: AsRef<[u8]>;
    type Error: Into<Box<dyn Error + Send + Sync>>;

    // Required methods
    fn set_headers(
        &self,
        protected_headers: &mut Headers,
        unprotected_headers: &mut Headers,
    ) -> Result<(), Self::Error>;
    fn sign(&self, data: &str) -> Result<Self::Signature, Self::Error>;
}

Available on crate features aws-lc and crypto only.

Signer implements all methods which are needed to sign our JWS requests, and add the needed info to our JOSE headers (JOSE headers = protected + unprotected headers)

Required Associated Types

type Signature: AsRef<[u8]>

type Error: Into<Box<dyn Error + Send + Sync>>

Required Methods

fn set_headers( &self, protected_headers: &mut Headers, unprotected_headers: &mut Headers, ) -> Result<(), Self::Error>

Set headers which are needed to verify the final Signature

Example headers are: alg, curve

fn sign(&self, data: &str) -> Result<Self::Signature, Self::Error>

Sign the str encoded payload

Dyn Compatibility

This trait is dyn compatible.

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