Enum TapSighashType

pub enum TapSighashType {
    Default = 0,
    All = 1,
    None = 2,
    Single = 3,
    AllPlusAnyoneCanPay = 129,
    NonePlusAnyoneCanPay = 130,
    SinglePlusAnyoneCanPay = 131,
}

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 = 0

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

All = 1

0x1: Sign all outputs.

None = 2

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

Single = 3

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 = 129

0x81: Sign all outputs but only this input.

NonePlusAnyoneCanPay = 130

0x82: Sign no outputs and only this input.

SinglePlusAnyoneCanPay = 131

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

fn from(s: EcdsaSighashType) -> TapSighashType

Converts to this type from the input type.

impl From<TapSighashType> for PsbtSighashType

fn from(taproot_hash_ty: TapSighashType) -> PsbtSighashType

impl Hash for TapSighashType

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

where __H: Hasher,

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 TapSighashType

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

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

impl PartialEq for TapSighashType

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

Tests for self and other values to be equal, and is used by ==.

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

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

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

Tests greater than (for self and other) and is used by the > operator.

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

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

impl Serialize for TapSighashType
