Struct Address 

pub struct Address(/* private fields */);

Fixed-width Ethereum address bytes.

Equality is constant-time because recovered sender checks appear in authentication and authorization paths.

The Hash implementation is for ordinary map/set use. Do not rely on hash-map lookup timing for secret or side-channel-sensitive access-control paths; use explicit indexed structures or constant-time scans there.

Implementations

impl Address

pub fn encoded_rlp_len(self) -> Result<usize, PrimitiveRlpError>

Returns the canonical RLP encoded length.

This is currently infallible for the fixed 20-byte address payload but keeps the same Result shape as the other primitive bridge helpers.

pub fn encode_rlp(self, output: &mut [u8]) -> Result<usize, PrimitiveRlpError>

Canonically encodes this address as a fixed-width scalar.

Returns the number of bytes written. output is not modified unless this function returns Ok.

pub fn try_from_rlp( input: &[u8], limits: DecodeLimits, ) -> Result<Self, PrimitiveRlpError>

Decodes exactly one fixed-width address scalar.

impl Address

pub const fn from_bytes(bytes: [u8; 20]) -> Self

Creates an address from raw bytes.

pub const fn to_bytes(self) -> [u8; 20]

Returns the raw address bytes.

pub fn ct_eq(&self, other: &Self) -> Choice

Compares two addresses in constant time.

Returns Choice so compound comparisons can use & and | without short-circuiting. Convert to bool only at the final trust boundary.

Trait Implementations

impl Clone for Address

fn clone(&self) -> Address

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for Address

impl Debug for Address

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

Formats the value using the given formatter.

impl Eq for Address

impl From<Address> for [u8; 20]

fn from(value: Address) -> Self

Converts to this type from the input type.

impl From<[u8; 20]> for Address

fn from(bytes: [u8; 20]) -> Self

Converts to this type from the input type.

impl Hash for Address

fn hash<H: Hasher>(&self, state: &mut H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for Address

fn eq(&self, other: &Self) -> 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.

impl RlpDecode for Address

type Error = PrimitiveRlpError

Error returned by this decoder.

fn decode_rlp(input: &[u8], limits: DecodeLimits) -> Result<Self, Self::Error>

Decodes exactly one canonical RLP item from input.

fn decode_rlp_item(item: RlpItem<'_>) -> Result<Self, Self::Error>

Decodes one already-bounded child item from an outer RLP list.

impl RlpEncode for Address

type Error = PrimitiveRlpError

Error returned by this encoder.

fn encoded_rlp_len(&self) -> Result<usize, Self::Error>

Returns the exact canonical RLP encoded length.

fn encode_rlp(&self, output: &mut [u8]) -> Result<usize, Self::Error>

Canonically encodes self into output.
