Struct bitcoin::util::misc::MessageSignature

pub struct MessageSignature {
    pub signature: RecoverableSignature,
    pub compressed: bool,
}

Available on crate feature secp-recovery only.

A signature on a Bitcoin Signed Message.

In order to use the to_base64 and from_base64 methods, as well as the fmt::Display and str::FromStr implementations, the base64 feature must be enabled.

Fields

signature: RecoverableSignature

The inner recoverable signature.

compressed: bool

Whether or not this signature was created with a compressed key.

Implementations

impl MessageSignature

pub fn new(signature: RecoverableSignature, compressed: bool) -> MessageSignature

Create a new MessageSignature.

pub fn serialize(&self) -> [u8; 65]

Serialize to bytes.

pub fn from_slice(
    bytes: &[u8]
) -> Result<MessageSignature, MessageSignatureError>

Create from a byte slice.

pub fn recover_pubkey<C: Verification>(
    &self,
    secp_ctx: &Secp256k1<C>,
    msg_hash: Hash
) -> Result<PublicKey, MessageSignatureError>

Attempt to recover a public key from the signature and the signed message.

To get the message hash from a message, use super::signed_msg_hash.

pub fn is_signed_by_address<C: Verification>(
    &self,
    secp_ctx: &Secp256k1<C>,
    address: &Address,
    msg_hash: Hash
) -> Result<bool, MessageSignatureError>

Verify that the signature signs the message and was signed by the given address.

To get the message hash from a message, use super::signed_msg_hash.

pub fn from_base64(s: &str) -> Result<MessageSignature, MessageSignatureError>

Available on crate feature base64 only.

Convert a signature from base64 encoding.

pub fn to_base64(&self) -> String

Available on crate feature base64 only.

Convert to base64 encoding.

Trait Implementations

impl Clone for MessageSignature

fn clone(&self) -> MessageSignature

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for MessageSignature

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

Formats the value using the given formatter.

impl Display for MessageSignature

Available on crate feature base64 only.

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

Formats the value using the given formatter.

impl FromStr for MessageSignature

Available on crate feature base64 only.

type Err = MessageSignatureError

The associated error which can be returned from parsing.

fn from_str(s: &str) -> Result<MessageSignature, MessageSignatureError>

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

impl PartialEq<MessageSignature> for MessageSignature

fn eq(&self, other: &MessageSignature) -> 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.
