Struct PublicKey 

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

Uncompressed secp256k1 public key (X || Y, 64 bytes).

Constructors accept the 33-byte SEC1-compressed encoding too.

Implementations

impl PublicKey

pub const LENGTH: usize = PUBLIC_KEY_LENGTH

Length in bytes when stored uncompressed.

pub fn new(b: &[u8]) -> Result<Self, Error>

Construct from bytes. Accepts 64-byte uncompressed (X || Y) or 33-byte compressed (SEC1).

pub fn from_hex(s: &str) -> Result<Self, Error>

Parse from hex (with or without 0x prefix). Length must be 33 (compressed) or 64 (uncompressed).

pub fn as_bytes(&self) -> &[u8]

Borrow the raw 64-byte uncompressed encoding.

pub fn to_hex(&self) -> String

Lowercase hex of the uncompressed encoding, no 0x prefix.

pub fn address(&self) -> EthAddress

Ethereum address: last 20 bytes of keccak256(X || Y).

pub fn compressed_bytes(&self) -> Result<[u8; 33], Error>

33-byte SEC1-compressed encoding.

pub fn compressed_hex(&self) -> Result<String, Error>

Lowercase hex of the compressed encoding, no 0x prefix.

Trait Implementations

impl Clone for PublicKey

fn clone(&self) -> PublicKey

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for PublicKey

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

Formats the value using the given formatter.

impl Display for PublicKey

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

Formats the value using the given formatter.

impl FromStr for PublicKey

type Err = Error

The associated error which can be returned from parsing.

fn from_str(s: &str) -> Result<Self, Self::Err>

Parses a string s to return a value of this type.

impl Hash for PublicKey

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 PublicKey

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