pub struct DerivedPubkey { /* private fields */ }
Expand description

A Pubkey with its derivation. Primarily used by PSBT.

Implementations§

source§

impl DerivedPubkey

source

pub fn to_sec1_bytes(&self) -> [u8; 33]

Get the compressed sec1 representation of the public key.

source§

impl DerivedPubkey

source

pub const fn new(key: VerifyingKey, derivation: KeyDerivation) -> Self
