Struct secp256k1::ecdsa::RecoverableSignature

pub struct RecoverableSignature(_);

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.
