Struct Signature

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

Represents a schnorr signature.

Implementations

impl Signature

pub fn from_byte_array(sig: [u8; 64]) -> Signature

Construct a Signature from a 64 bytes array.

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

👎Deprecating in a future version: Use from_byte_array instead.

Creates a Signature directly from a slice.

pub fn serialize(&self) -> [u8; 64]

👎Deprecated since 0.30.0: Use to_byte_array instead.

Returns a signature as a byte array.

pub fn to_byte_array(self) -> [u8; 64]

Returns a signature as a byte array.

pub fn as_byte_array(&self) -> &[u8; 64]

Returns a signature as a byte array.

pub fn verify(&self, msg: &[u8], pk: &XOnlyPublicKey) -> Result<(), Error>

Available on crate feature global-context only.

Verifies a schnorr signature for msg using pk and the global SECP256K1 context.

Trait Implementations

impl AsRef<[u8; 64]> for Signature

fn as_ref(&self) -> &[u8; 64]

Gets a reference to the underlying array

impl CPtr for Signature

impl<'de> Deserialize<'de> for Signature

Available on crate feature serde only.

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

where D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for Signature

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

Formats the value using the given formatter.

impl FromStr for Signature

type Err = Error

The associated error which can be returned from parsing.

fn from_str(s: &str) -> Result<Signature, Error>

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

impl Hash for Signature

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

where __H: Hasher,

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<I> Index<I> for Signature

where [u8]: Index<I>,

type Output = <[u8] as Index<I>>::Output

The returned type after indexing.

fn index(&self, index: I) -> &<Signature as Index<I>>::Output

Performs the indexing (container[index]) operation.

impl LowerHex for Signature

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

Formats the value using the given formatter.

impl Ord for Signature

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

fn eq(&self, other: &Signature) -> 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 Signature

fn partial_cmp(&self, other: &Signature) -> 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 Signature

Available on crate feature serde only.

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

where S: Serializer,

Serialize this value into the given Serde serializer.
