Trait Authorization

pub trait Authorization: Clone {
    // Required methods
    fn authority(&self) -> Option<Address>;
    fn chain_id(&self) -> u64;
    fn nonce(&self) -> u64;
    fn address(&self) -> Address;
    fn is_invalid(&self) -> bool;
}

Authorization trait.

Required Methods

fn authority(&self) -> Option<Address>

Authority address.

Note

Authority signature can be invalid, so this method returns None if the authority could not be recovered.

Valid signature Parity should be 0 or 1 and signature s-value should be less than SECP256K1N_HALF.

fn chain_id(&self) -> u64

Returns authorization the chain id.

fn nonce(&self) -> u64

Returns the nonce.

Note

If nonce is not same as the nonce of the signer account, the authorization is skipped.

fn address(&self) -> Address

Returns the address that this account is delegated to.

fn is_invalid(&self) -> bool

Returns true if the authorization is valid.

Temporary method needed for older EIP spec and will removed in future when test get updated.

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.

Implementations on Foreign Types

impl Authorization for RecoveredAuthorization

fn authority(&self) -> Option<Address>

Authority address. Obtained by recovering of the signature.

fn chain_id(&self) -> u64

Returns authorization the chain id.

fn nonce(&self) -> u64

Returns the nonce.

Note

If nonce is not same as the nonce of the signer account, authorization is skipped and considered invalidated.

fn address(&self) -> Address

Returns the address that this account should delegate to.

fn is_invalid(&self) -> bool

Returns true if the authorization is valid.

Temporary method needed for older EIP spec and will removed in future
