Expand description
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
TapSighashType
).
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
impl EcdsaSighashType
pub fn from_consensus(n: u32) -> EcdsaSighashType
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_standard(
n: u32
) -> Result<EcdsaSighashType, NonStandardSighashTypeError>
pub fn from_standard( n: u32 ) -> Result<EcdsaSighashType, NonStandardSighashTypeError>
pub fn to_u32(self) -> u32
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.
