Struct SighashType 

pub struct SighashType(pub u8);

SIGHASH types for transaction signature verification

IMPORTANT: The enum values match the canonical sighash bytes used in sighash computation. Early Bitcoin allowed sighash type 0x00 (treated as SIGHASH_ALL behavior), which we Wraps the raw sighash byte from the signature, preserving its exact value for preimage serialization. consensus uses the raw byte directly in the sighash preimage — before STRICTENC activation (BIP66), ANY sighash byte was accepted. The base type is determined by masking with 0x1f: NONE=2, SINGLE=3, else ALL.

Implementations

impl SighashType

pub const ALL_LEGACY: SighashType

pub const ALL: SighashType

pub const NONE: SighashType

pub const SINGLE: SighashType

pub const ALL_ANYONECANPAY: SighashType

pub const NONE_ANYONECANPAY: SighashType

pub const SINGLE_ANYONECANPAY: SighashType

pub fn from_byte(byte: u8) -> SighashType

Create from raw sighash byte — accepts ANY value (pre-STRICTENC compatibility). consensus determines behavior from byte & 0x1f and uses the raw byte in the preimage.

pub fn as_u32(&self) -> u32

Raw byte value for preimage serialization

pub fn base_type(&self) -> u8

Base sighash type (lower 5 bits), matching consensus’s nHashType & 0x1f

pub fn is_anyonecanpay(&self) -> bool

Whether ANYONECANPAY flag is set (bit 7)

pub fn is_all(&self) -> bool

Whether this has SIGHASH_ALL behavior (base type is not NONE or SINGLE)

pub fn is_none(&self) -> bool

Whether base type is SIGHASH_NONE

pub fn is_single(&self) -> bool

Whether base type is SIGHASH_SINGLE

Trait Implementations

impl Clone for SighashType

fn clone(&self) -> SighashType

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for SighashType

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

Formats the value using the given formatter.

impl Hash for SighashType

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 SighashType

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