Enum bdk_chain::bitcoin::TapSighashType

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.

Variants§

§

Default = 0

0x0: Used when not explicitly specified, defaults to TapSighashType::All

§

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).
