Implementations

impl CompressedPublicKey

pub fn pubkey_hash(&self) -> PubkeyHash

Returns bitcoin 160-bit hash of the public key

pub fn wpubkey_hash(&self) -> WPubkeyHash

Returns bitcoin 160-bit hash of the public key for witness program

pub fn p2wpkh_script_code(&self) -> ScriptBuf

Returns the script code used to spend a P2WPKH input.

pub fn write_into<W>(&self, writer: &mut W) -> Result<(), Error>

where W: Write + ?Sized,

Write the public key into a writer

pub fn read_from<R>(reader: &mut R) -> Result<CompressedPublicKey, Error>

where R: Read + ?Sized,

Read the public key from a reader

This internally reads the first byte before reading the rest, so use of a BufReader is recommended.

pub fn to_bytes(&self) -> [u8; 33]

Serializes the public key.

As the type name suggests, the key is serialzied in compressed format.

Note that this can be used as a sort key to get BIP67-compliant sorting. That’s why this type doesn’t have the to_sort_key method - it would duplicate this one.

pub fn from_slice(data: &[u8]) -> Result<CompressedPublicKey, Error>

Deserialize a public key from a slice

pub fn from_private_key<C>( secp: &Secp256k1<C>, sk: &PrivateKey ) -> Result<CompressedPublicKey, UncompressedPublicKeyError>

where C: Signing,

Computes the public key as supposed to be used with this secret

pub fn verify<C>( &self, secp: &Secp256k1<C>, msg: &Message, sig: &Signature ) -> Result<(), Error>

where C: Verification,

Checks that sig is a valid ECDSA signature for msg using this public key.

type Err = ParseCompressedPublicKeyError

The associated error which can be returned from parsing.

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

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

impl Ord for CompressedPublicKey

fn cmp(&self, other: &CompressedPublicKey) -> 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.

impl PartialEq for CompressedPublicKey

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