Expand description

Version of the segregated witness program.

Helps limit possible versions of the witness according to the specification. If a plain u8 type was used instead it would mean that the version may be > 16, which would be incorrect.

First byte of scriptPubkey in transaction output for transactions starting with opcodes ranging from 0 to 16 (inclusive).

Implementations§

§

impl WitnessVersion

pub fn to_num(self) -> u8

Returns integer version number representation for a given WitnessVersion value.

NB: this is not the same as an integer representation of the opcode signifying witness version in bitcoin script. Thus, there is no function to directly convert witness version into a byte since the conversion requires context (bitcoin script or just a version number).

pub fn to_fe(self) -> Fe32

Converts this witness version to a GF32 field element.
