Struct PublicKey

pub struct PublicKey {
    pub compressed: bool,
    pub key: PublicKey,
}

A Bitcoin ECDSA public key

Fields

compressed: bool

Whether this public key should be serialized as compressed

key: PublicKey

The actual ECDSA key

Implementations

impl PublicKey

pub fn pubkey_hash(&self, secp: &Secp256k1) -> PubkeyHash

Returns bitcoin 160-bit hash of the public key

pub fn wpubkey_hash(&self, secp: &Secp256k1) -> Option<WPubkeyHash>

Returns bitcoin 160-bit hash of the public key for witness program

pub fn write_into<W: Write>( &self, secp: &Secp256k1, writer: W, ) -> Result<(), Error>

Write the public key into a writer

pub fn read_from<R: Read>(secp: &Secp256k1, reader: R) -> Result<Self, Error>

Read the public key from a reader

This internally reads the first byte before reading the rest, so use of a BufReader is recommended.

pub fn to_bytes(&self, secp: &Secp256k1) -> Vec<u8>

Serialize the public key to bytes

pub fn from_slice(secp: &Secp256k1, data: &[u8]) -> Result<PublicKey, Error>

Deserialize a public key from a slice

pub fn from_private_key(secp: &Secp256k1, sk: &PrivateKey) -> PublicKey

Computes the public key as supposed to be used with this secret

Trait Implementations

impl Clone for PublicKey

fn clone(&self) -> PublicKey

Returns a copy 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 Deserialize for PublicKey

fn deserialize(bytes: &[u8]) -> Result<Self, Error>

Deserialize a value from raw data.

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<PublicKey, Error>

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 Ord for PublicKey

fn cmp(&self, other: &PublicKey) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

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.

impl PartialOrd for PublicKey

fn partial_cmp(&self, other: &PublicKey) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.

impl Serialize for PublicKey

fn serialize(&self) -> Vec<u8>

Serialize a value as raw data.
