Struct Signature 

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

Compressed-form Secp256k1 signature.

Implementations

impl Signature

pub const LEN: usize = Bytes64::LEN

Memory length of the type in bytes.

pub fn from_bytes(bytes: [u8; 64]) -> Signature

Construct a Signature directly from its bytes.

This constructor expects the given bytes to be a valid signature. No signing is performed.

pub fn from_bytes_ref(bytes: &[u8; 64]) -> &Signature

Construct a Signature reference directly from a reference to its bytes.

This constructor expects the given bytes to be a valid signature. No signing is performed.

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

Removes the recovery id from the signature.

pub fn from_bytes_unchecked(bytes: [u8; 64]) -> Signature

👎Deprecated:

Use Signature::from_bytes instead

Kept temporarily for backwards compatibility.

impl Signature

Secp256k1 methods

pub fn sign(secret: &SecretKey, message: &Message) -> Signature

Produce secp256k1 signature

pub fn recover(&self, message: &Message) -> Result<PublicKey, Error>

Recover secp256k1 public key from a signature performed with

pub fn verify( &self, public_key: &PublicKey, message: &Message, ) -> Result<(), Error>

Verify that a signature matches given public key

Trait Implementations

impl AsMut<[u8]> for Signature

fn as_mut(&mut self) -> &mut [u8]

Converts this type into a mutable reference of the (usually inferred) input type.

impl AsRef<[u8]> for Signature

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

Converts this type into a shared reference of the (usually inferred) input type.

impl Clone for Signature

fn clone(&self) -> Signature

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Signature

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

Formats the value using the given formatter.

impl Default for Signature

fn default() -> Signature

Returns the “default value” for a type.

impl Deref for Signature

type Target = [u8; 64]

The resulting type after dereferencing.

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

Dereferences the value.

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

fn deserialize<__D>( __deserializer: __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 From<Signature> for [u8; 64]

fn from(salt: Signature) -> [u8; 64]

Converts to this type from the input type.

impl From<Signature> for Bytes64

fn from(s: Signature) -> Bytes64

Converts to this type from the input type.

impl FromStr for Signature

fn from_str(s: &str) -> Result<Signature, <Signature as FromStr>::Err>

Parse a Signature directly from its bytes encoded as hex in a string.

This constructor does not perform any signing.

type Err = Error

The associated error which can be returned from parsing.

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 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

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

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl UpperHex for Signature

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

Formats the value using the given formatter.
