Trait Verify

pub trait Verify {
    type Signer: IdentifyAccount;

    // Required method
    fn verify<L>(
        &self,
        msg: L,
        signer: &<Self::Signer as IdentifyAccount>::AccountId,
    ) -> bool
       where L: Lazy<[u8]>;
}

Means of signature verification.

Required Associated Types

type Signer: IdentifyAccount

Type of the signer.

Required Methods

fn verify<L>( &self, msg: L, signer: &<Self::Signer as IdentifyAccount>::AccountId, ) -> bool

where L: Lazy<[u8]>,

Verify a signature.

Return true if signature is valid for the value.

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.
