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
impl WitnessVersion
pub fn to_num(self) -> u8
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
pub fn to_fe(self) -> Fe32
Converts this witness version to a GF32 field element.
