Struct psbt::PsbtSighashType

pub struct PsbtSighashType { /* private fields */ }

A Signature hash type for the corresponding input. As of taproot upgrade, the signature hash type can be either EcdsaSighashType or SchnorrSighashType but it is not possible to know directly which signature hash type the user is dealing with. Therefore, the user is responsible for converting to/from PsbtSighashType from/to the desired signature hash type they need.

Implementations

impl PsbtSighashType

pub fn ecdsa_hash_ty(self) -> Result<EcdsaSighashType, NonStandardSighashType>

Returns the EcdsaSighashType if the PsbtSighashType can be converted to one.

pub fn schnorr_hash_ty(self) -> Result<SchnorrSighashType, Error>

Returns the SchnorrSighashType if the PsbtSighashType can be converted to one.

pub fn from_u32(n: u32) -> PsbtSighashType

Creates a PsbtSighashType from a raw u32.

Allows construction of a non-standard or non-valid sighash flag (EcdsaSighashType, SchnorrSighashType respectively).

pub fn to_u32(self) -> u32

Converts PsbtSighashType to a raw u32 sighash flag.

No guarantees are made as to the standardness or validity of the returned value.

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 PsbtSighashType

fn cmp(&self, other: &PsbtSighashType) -> 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 + PartialOrd,

Restrict a value to a certain interval.

impl PartialEq for PsbtSighashType

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

impl PartialOrd for PsbtSighashType

fn partial_cmp(&self, other: &PsbtSighashType) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

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

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

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

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

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

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

impl Serialize for PsbtSighashType

fn serialize(&self) -> Vec<u8>

Serialize a value as raw data.

impl StrictDecode for PsbtSighashType

fn strict_decode<D>(d: D) -> Result<PsbtSighashType, Error>

where D: Read,

Decode with the given std::io::Read instance; must either construct an instance or return implementation-specific error type.

fn strict_deserialize(data: impl AsRef<[u8]>) -> Result<Self, Error>

Tries to deserialize byte array into the current type using StrictDecode::strict_decode. If there are some data remains in the buffer once deserialization is completed, fails with Error::DataNotEntirelyConsumed. Use io::Cursor over the buffer and StrictDecode::strict_decode to avoid such failures.

fn strict_file_load(path: impl AsRef<Path>) -> Result<Self, Error>

Reads data from file at path and reconstructs object from it. Fails with Error::DataNotEntirelyConsumed if file contains remaining data after the object reconstruction.

impl StrictEncode for PsbtSighashType

fn strict_encode<E>(&self, e: E) -> Result<usize, Error>

where E: Write,

Encode with the given std::io::Write instance; must return result with either amount of bytes encoded – or implementation-specific error type.

fn strict_serialize(&self) -> Result<Vec<u8>, Error>

Serializes data as a byte array using StrictEncode::strict_encode function

fn strict_file_save(&self, path: impl AsRef<Path>) -> Result<usize, Error>

Saves data to a file at a given path. If the file does not exists, attempts to create the file. If the file already exists, it gets truncated.
