Struct TweakedPublicKey

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

Tweaked BIP-340 X-coord-only public key

Implementations

impl TweakedPublicKey

pub fn from_keypair(keypair: TweakedKeypair) -> TweakedPublicKey

Returns the TweakedPublicKey for keypair.

pub fn dangerous_assume_tweaked(key: XOnlyPublicKey) -> TweakedPublicKey

Creates a new TweakedPublicKey from a XOnlyPublicKey. No tweak is applied, consider calling tap_tweak on an UntweakedPublicKey instead of using this constructor.

This method is dangerous and can lead to loss of funds if used incorrectly. Specifically, in multi-party protocols a peer can provide a value that allows them to steal.

pub fn to_x_only_public_key(self) -> XOnlyPublicKey

Returns the underlying x-only public key.

pub fn as_x_only_public_key(&self) -> &XOnlyPublicKey

Returns a reference to the underlying x-only public key.

pub fn serialize(&self) -> [u8; 32]

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.

Trait Implementations

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for TweakedPublicKey

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

Formats the value using the given formatter.

impl From<TweakedKeypair> for TweakedPublicKey

fn from(pair: TweakedKeypair) -> TweakedPublicKey

Converts to this type from the input type.

impl From<TweakedPublicKey> for XOnlyPublicKey

impl Ord for TweakedPublicKey

fn cmp(&self, other: &TweakedPublicKey) -> 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,

impl PartialEq for TweakedPublicKey

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

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 TweakedPublicKey

fn serialize<__S>( &self, __serializer: __S, ) -> Result<<__S as Serializer>::Ok, <__S as Serializer>::Error>

where __S: Serializer,
