Enum breez_sdk_liquid::bitcoin::blockdata::transaction::EcdsaSighashType

pub enum EcdsaSighashType {
    All = 1,
    None = 2,
    Single = 3,
    AllPlusAnyoneCanPay = 129,
    NonePlusAnyoneCanPay = 130,

}

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 (see also [SchnorrSighashType]).

Variants

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).

Implementations

impl EcdsaSighashType

pub fn from_u32_consensus(n: u32) -> EcdsaSighashType

👎Deprecated since 0.28.0: please use from_consensus

Creates a EcdsaSighashType from a raw u32.

pub fn from_consensus(n: u32) -> EcdsaSighashType

Creates a EcdsaSighashType from a raw u32.

Note: this replicates consensus behaviour, for current standardness rules correctness you probably want Self::from_standard.

This might cause unexpected behavior because it does not roundtrip. That is, EcdsaSighashType::from_consensus(n) as u32 != n for non-standard values of n. While verifying signatures, the user should retain the n and use it compute the signature hash message.

pub fn from_u32_standard( n: u32, ) -> Result<EcdsaSighashType, NonStandardSighashType>

👎Deprecated since 0.28.0: please use from_standard

Creates a EcdsaSighashType from a raw u32.

pub fn from_standard(n: u32) -> Result<EcdsaSighashType, NonStandardSighashType>

Creates a EcdsaSighashType from a raw u32.

Errors

If n is a non-standard sighash value.

pub fn to_u32(self) -> u32

Converts EcdsaSighashType to a u32 sighash flag.

The returned value is guaranteed to be a valid according to standardness rules.

Trait Implementations

impl Clone for EcdsaSighashType

fn clone(&self) -> EcdsaSighashType

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for EcdsaSighashType

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl Display for EcdsaSighashType

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl From<EcdsaSighashType> for PsbtSighashType

fn from(ecdsa_hash_ty: EcdsaSighashType) -> PsbtSighashType

Converts to this type from the input type.

impl From<EcdsaSighashType> for SchnorrSighashType

fn from(s: EcdsaSighashType) -> SchnorrSighashType

Converts to this type from the input type.

impl FromStr for EcdsaSighashType

type Err = SighashTypeParseError

The associated error which can be returned from parsing.

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

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

impl Hash for EcdsaSighashType

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 PartialEq for EcdsaSighashType

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