Struct Authorization 

pub struct Authorization {
    pub authority: H160,
    pub address: H160,
    pub nonce: u64,
    pub is_valid: bool,
}

Authorization contains already prepared data for EIP-7702.

• authorityis ecrecovered authority address.
• address is delegation destination address.
• nonce is the nonce value which authority.nonce should be equal.
• is_valid is the flag that indicates the validity of the authorization. It is used to charge gas for each authorization item, but if it’s invalid exclude from EVM authority_list flow.

Fields

authority: H160

address: H160

nonce: u64

is_valid: bool

Implementations

impl Authorization

pub const fn new( authority: H160, address: H160, nonce: u64, is_valid: bool, ) -> Self

Create a new Authorization with given authority, address, and nonce.

pub fn is_delegated(code: &[u8]) -> bool

Returns true if authority is delegated to address. 0xef0100 ++ address, and it is always 23 bytes.

pub fn get_delegated_address(code: &[u8]) -> Option<H160>

Get authority delegated address. It checks, is it delegation designation (EIP-7702).

pub fn delegation_code(&self) -> Vec<u8>

Returns the delegation code as composing: 0xef0100 ++ address. Result code is always 23 bytes.

Trait Implementations

impl Clone for Authorization

fn clone(&self) -> Authorization

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Authorization

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for Authorization

fn default() -> Authorization

Returns the “default value” for a type.

impl PartialEq for Authorization

fn eq(&self, other: &Authorization) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
