Struct secp256k1::key::PublicKey

pub struct PublicKey(_);

A Secp256k1 public key, used for verification of signatures

Implementations

impl PublicKey

pub fn as_ptr(&self) -> *const PublicKey

Obtains a raw pointer suitable for use with FFI functions

pub fn from_secret_key<C: Signing>(
    secp: &Secp256k1<C>,
    sk: &SecretKey
) -> PublicKey

Creates a new public key from a secret key.

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

Creates a public key directly from a slice

pub fn serialize(&self) -> [u8; 33]

Serialize the key as a byte-encoded pair of values. In compressed form the y-coordinate is represented by only a single bit, as x determines it up to one bit.

pub fn serialize_uncompressed(&self) -> [u8; 65]

Serialize the key as a byte-encoded pair of values, in uncompressed form

pub fn add_exp_assign<C: Verification>(
    &mut self,
    secp: &Secp256k1<C>,
    other: &SecretKey
) -> Result<(), Error>

Adds the pk corresponding to other to the pk self in place

pub fn mul_assign<C: Verification>(
    &mut self,
    secp: &Secp256k1<C>,
    other: &SecretKey
) -> Result<(), Error>

Muliplies the pk self in place by the scalar other

pub fn combine<C>(
    &self,
    secp: &Secp256k1<C>,
    other: &PublicKey
) -> Result<PublicKey, Error>

Adds a second key to this one, returning the sum. Returns an error if the result would be the point at infinity, i.e. we are adding this point to its own negation

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<'de> Deserialize<'de> for PublicKey

fn deserialize<D: Deserializer<'de>>(d: D) -> Result<PublicKey, D::Error>

Deserialize this value from the given Serde deserializer.

impl Display for PublicKey

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

Formats the value using the given formatter.

impl From<PublicKey> for PublicKey

Creates a new public key from a FFI public key

fn from(pk: PublicKey) -> PublicKey

Converts to this type from the input type.

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) -> Selfwhere
    Self: Sized,

Compares and returns the maximum of two values.

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

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Selfwhere
    Self: Sized + PartialOrd<Self>,

Restrict a value to a certain interval.

impl PartialEq<PublicKey> for PublicKey

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

This method tests for self and other values to be equal, and is used by ==.

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

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

impl PartialOrd<PublicKey> 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

This method tests less than (for self and other) and is used by the < operator.

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

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

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

This method tests greater than (for self and other) and is used by the > operator.

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

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

impl Serialize for PublicKey

fn serialize<S: Serializer>(&self, s: S) -> Result<S::Ok, S::Error>

Serialize this value into the given Serde serializer.

impl Copy for PublicKey

impl Eq for PublicKey

impl StructuralEq for PublicKey
