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

pub fn from_u5(value: u5) -> Result<WitnessVersion, Error>

👎Deprecated since 0.29.0: use try_from instead

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

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

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

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

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

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

Determines the checksum variant. See BIP-0350 for specification.
