Enum sapio_bitcoin::blockdata::transaction::EcdsaSigHashType

}

Hashtype of an input’s signature, encoded in the last byte of the signature Fixed values so they can be casted as integer types for encoding See also crate::SchnorrSigHashType

Variants

All

0x1: Sign all outputs

None

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

Single

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

0x81: Sign all outputs but only this input

NonePlusAnyoneCanPay

0x82: Sign no outputs and only this input

SinglePlusAnyoneCanPay

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

Implementations

impl EcdsaSigHashType

pub fn from_u32(n: u32) -> EcdsaSigHashType

👎 Deprecated since 0.26.1:

please use from_u32_consensus or from_u32_standard instead

Reads a 4-byte uint32 as a sighash type.

pub fn from_u32_consensus(n: u32) -> EcdsaSigHashType

Reads a 4-byte uint32 as a sighash type.

Note: this replicates consensus behaviour, for current standardness rules correctness you probably want Self::from_u32_standard. This might cause unexpected behavior because it does not roundtrip. That is, EcdsaSigHashType::from_u32_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>

Read a 4-byte uint32 as a standard sighash type, returning an error if the type is non standard.

pub fn as_u32(self) -> u32

Converts to a u32
