Enum bitcoin::util::sighash::SchnorrSighashType

pub enum SchnorrSighashType {
    Default,
    All,
    None,
    Single,
    AllPlusAnyoneCanPay,
    NonePlusAnyoneCanPay,
    SinglePlusAnyoneCanPay,
}

Hashtype of an input’s signature, encoded in the last byte of the signature. Fixed values so they can be cast as integer types for encoding.

Variants

Default

0x0: Used when not explicitly specified, defaults to SchnorrSighashType::All

All

0x1: Sign all outputs.

None

0x2: Sign no outputs — anyone can choose the destination.

Single

0x3: Sign the output whose index matches this input’s index. If none exists, sign the hash 0000000000000000000000000000000000000000000000000000000000000001. (This rule is probably an unintentional C++ism, but it’s consensus so we have to follow it.)

AllPlusAnyoneCanPay

0x81: Sign all outputs but only this input.

NonePlusAnyoneCanPay

0x82: Sign no outputs and only this input.

SinglePlusAnyoneCanPay

0x83: Sign one output and only this input (see Single for what “one output” means).

Implementations

fn from(s: EcdsaSighashType) -> Self

Converts to this type from the input type.

impl From<SchnorrSighashType> for PsbtSighashType

fn from(schnorr_hash_ty: SchnorrSighashType) -> Self

impl FromStr for SchnorrSighashType

type Err = SighashTypeParseError

The associated error which can be returned from parsing.

fn from_str(s: &str) -> Result<Self, Self::Err>

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

impl Hash for SchnorrSighashType

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

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

Feeds a slice of this type into the given Hasher.

impl Ord for SchnorrSighashType

fn cmp(&self, other: &SchnorrSighashType) -> Ordering

This method returns an Ordering between self and other.

const fn max(self, other: Self) -> Selfwhere
    Self: Sized,

Compares and returns the maximum of two values.

const fn min(self, other: Self) -> Selfwhere
    Self: Sized,

Compares and returns the minimum of two values.

const fn clamp(self, min: Self, max: Self) -> Selfwhere
    Self: Sized + PartialOrd<Self>,

Restrict a value to a certain interval.

impl PartialEq<SchnorrSighashType> for SchnorrSighashType

fn eq(&self, other: &SchnorrSighashType) -> bool

This method tests for self and other values to be equal, and is used by ==.

const 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.

This method tests less than or equal to (for self and other) and is used by the <= operator.

const fn gt(&self, other: &Rhs) -> bool

This method tests greater than (for self and other) and is used by the > operator.

const fn ge(&self, other: &Rhs) -> bool

This method tests greater than or equal to (for self and other) and is used by the >= operator.
