Trait Key 

pub trait Key {
    const ALG: &'static str;

    // Provided method
    fn check_alg(alg: &str) -> Result<(), Error> { ... }
}

What SigningKey and VerifyingKey have in common.

Required Associated Constants

const ALG: &'static str

value for alg in the JWT header

Provided Methods

fn check_alg(alg: &str) -> Result<(), Error>

Checks that alg equals Self::ALG.

This method is overriden by IgnoreSignature.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
