Trait polkadot_sdk_frame::traits::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.
