Struct secp256k1::ecdsa::RecoverableSignature

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

An ECDSA signature with a recovery ID for pubkey recovery.

Implementations

impl RecoverableSignature

pub fn from_compact( data: &[u8], recid: RecoveryId, ) -> Result<RecoverableSignature, Error>

Converts a compact-encoded byte slice to a signature. This representation is nonstandard and defined by the libsecp256k1 library.

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

👎Deprecated since 0.25.0: Use Self::as_c_ptr if you need to access the FFI layer

Obtains a raw pointer suitable for use with FFI functions.

pub fn as_mut_ptr(&mut self) -> *mut RecoverableSignature

👎Deprecated since 0.25.0: Use Self::as_mut_c_ptr if you need to access the FFI layer

Obtains a raw mutable pointer suitable for use with FFI functions.

pub fn serialize_compact(&self) -> (RecoveryId, [u8; 64])

Serializes the recoverable signature in compact format.

pub fn to_standard(&self) -> Signature

Converts a recoverable signature to a non-recoverable one (this is needed for verification).

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

Determines the public key for which this Signature is valid for msg. Requires a verify-capable context.

Trait Implementations

impl CPtr for RecoverableSignature

type Target = RecoverableSignature

fn as_mut_c_ptr(&mut self) -> *mut Self::Target

impl Clone for RecoverableSignature

fn clone(&self) -> RecoverableSignature

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for RecoverableSignature

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

Formats the value using the given formatter.

impl From<RecoverableSignature> for RecoverableSignature

Creates a new recoverable signature from a FFI one.

fn from(sig: RecoverableSignature) -> RecoverableSignature

Converts to this type from the input type.

impl Hash for RecoverableSignature

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 RecoverableSignature

fn cmp(&self, other: &RecoverableSignature) -> 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 + PartialOrd,

Restrict a value to a certain interval.

impl PartialEq for RecoverableSignature

fn eq(&self, other: &RecoverableSignature) -> 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 for RecoverableSignature

fn partial_cmp(&self, other: &RecoverableSignature) -> 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.
