A type that can recover the signer of a transaction.

This is a helper trait that only provides the ability to recover the signer (address) of a transaction.

Required Methods

fn recover_signer(&self) -> Result<Address, RecoveryError>

Recover signer from signature and hash.

Returns an error if the transaction’s signature is invalid following EIP-2.

Note:

This can fail for some early ethereum mainnet transactions pre EIP-2, use Self::recover_signer_unchecked if you want to recover the signer without ensuring that the signature has a low s value.

fn recover_signer_unchecked(&self) -> Result<Address, RecoveryError>

Recover signer from signature and hash without ensuring that the signature has a low s value.

Returns an error if the transaction’s signature is invalid.

Provided Methods

fn try_into_recovered(self) -> Result<Recovered<Self>, RecoveryError>

where Self: Sized,

Recover the signer via SignerRecoverable::recover_signer and returns a Recovered<Self>

fn try_into_recovered_unchecked(self) -> Result<Recovered<Self>, RecoveryError>

where Self: Sized,

Recover the signer via SignerRecoverable::recover_signer_unchecked and returns a Recovered<&Self>

fn try_to_recovered_ref(&self) -> Result<Recovered<&Self>, RecoveryError>

Recover the signer via SignerRecoverable::recover_signer and returns a Recovered<&Self>

fn try_to_recovered_ref_unchecked( &self, ) -> Result<Recovered<&Self>, RecoveryError>

Recover the signer via SignerRecoverable::recover_signer_unchecked and returns a Recovered<&Self>

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.
