Struct bdk_chain::bitcoin::TapTweakHash
pub struct TapTweakHash(/* private fields */);
Expand description
Taproot-tagged hash with tag "TapTweak".
This hash type is used while computing the tweaked public key.
Implementations§
§impl TapTweakHash
impl TapTweakHash
pub fn from_raw_hash(inner: Hash<TapTweakTag>) -> TapTweakHash
pub fn from_raw_hash(inner: Hash<TapTweakTag>) -> TapTweakHash
Creates this wrapper type from the inner hash type.
pub fn to_raw_hash(self) -> Hash<TapTweakTag>
pub fn to_raw_hash(self) -> Hash<TapTweakTag>
Returns the inner hash (sha256, sh256d etc.).
pub fn as_raw_hash(&self) -> &Hash<TapTweakTag>
pub fn as_raw_hash(&self) -> &Hash<TapTweakTag>
Returns a reference to the inner hash (sha256, sh256d etc.).
§impl TapTweakHash
impl TapTweakHash
pub fn from_key_and_tweak(
internal_key: XOnlyPublicKey,
merkle_root: Option<TapNodeHash>
) -> TapTweakHash
pub fn from_key_and_tweak( internal_key: XOnlyPublicKey, merkle_root: Option<TapNodeHash> ) -> TapTweakHash
Creates a new BIP341 TapTweakHash
from key and tweak. Produces H_taptweak(P||R)
where
P
is the internal key and R
is the merkle root.

§type Engine = <Hash<TapTweakTag> as Hash>::Engine
type Engine = <Hash<TapTweakTag> as Hash>::Engine

to implement the
io::Write
trait, and to never return errors under
any conditions.§const DISPLAY_BACKWARD: bool = false
const DISPLAY_BACKWARD: bool = false
Flag indicating whether user-visible serializations of this hash
should be backward. For some reason Satoshi decided this should be
true for
