Expand description
Version of the 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 from_u5(value: u5) -> Result<WitnessVersion, Error>
👎Deprecated since 0.29.0: use try_from instead
pub fn from_u5(value: u5) -> Result<WitnessVersion, Error>
Converts 5-bit unsigned integer value matching single symbol from Bech32(m) address encoding
(bech32::u5
) into WitnessVersion
variant.
§Returns
Version of the Witness program.
§Errors
If the integer does not correspond to any witness version, errors with
Error::InvalidWitnessVersion
.
pub fn from_num(no: u8) -> Result<WitnessVersion, Error>
👎Deprecated since 0.29.0: use try_from instead
pub fn from_num(no: u8) -> Result<WitnessVersion, Error>
Converts an 8-bit unsigned integer value into WitnessVersion
variant.
§Returns
Version of the Witness program.
§Errors
If the integer does not correspond to any witness version, errors with
Error::InvalidWitnessVersion
.
pub fn from_opcode(opcode: All) -> Result<WitnessVersion, Error>
👎Deprecated since 0.29.0: use try_from instead
pub fn from_opcode(opcode: All) -> Result<WitnessVersion, Error>
Converts bitcoin script opcode into WitnessVersion
variant.
§Returns
Version of the Witness program (for opcodes in range of OP_0
..OP_16
).
§Errors
If the opcode does not correspond to any witness version, errors with
Error::MalformedWitnessVersion
.
pub fn from_instruction(
instruction: Instruction<'_>,
) -> Result<WitnessVersion, Error>
👎Deprecated since 0.29.0: use try_from instead
pub fn from_instruction( instruction: Instruction<'_>, ) -> Result<WitnessVersion, Error>
Converts bitcoin script Instruction
(parsed opcode) into WitnessVersion
variant.
§Returns
Version of the Witness program for Instruction::Op
and Instruction::PushBytes
with
byte value within 1..=16
range.
§Errors
If the opcode does not correspond to any witness version, errors with
Error::MalformedWitnessVersion
for the rest of opcodes.
pub fn into_num(self) -> u8
👎Deprecated since 0.29.0: use to_num instead
pub fn into_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_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 bech32_variant(&self) -> Variant
pub fn bech32_variant(&self) -> Variant
Determines the checksum variant. See BIP-0350 for specification.
