Struct secp256k1::ecdsa::RecoverableSignature

pub struct RecoverableSignature(_);

Available on crate feature recovery only.

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

Obtains a raw pointer suitable for use with FFI functions.

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

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>

Available on crate feature global-context only.

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_c_ptr(&self) -> *const Self::Target

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 PartialEq<RecoverableSignature> 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.
