Implementations

impl WitnessVer

pub fn from_op_code(op_code: OpCode) -> Result<WitnessVer, SegwitError>

Converts bitcoin script opcode into WitnessVer variant.

Errors

If the opcode does not correspond to any witness version, errors with SegwitError::MalformedWitnessVersion.

pub fn from_version_no(no: u8) -> Result<WitnessVer, SegwitError>

Converts witness version ordinal number into WitnessVer variant.

Errors

If the witness version number exceeds 16, errors with SegwitError::MalformedWitnessVersion.

pub fn op_code(self) -> OpCode

Converts WitnessVer instance into corresponding Bitcoin op-code.

pub fn version_no(self) -> u8

Converts WitnessVer into ordinal version number.

Trait Implementations

impl Clone for WitnessVer

fn clone(&self) -> WitnessVer

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for WitnessVer

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl Display for WitnessVer

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl Hash for WitnessVer

fn hash<__H>(&self, state: &mut __H)

where __H: Hasher,

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Ord for WitnessVer

fn cmp(&self, other: &WitnessVer) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized + PartialOrd,

Restrict a value to a certain interval.

impl PartialEq for WitnessVer

fn eq(&self, other: &WitnessVer) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

fn partial_cmp(&self, other: &WitnessVer) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Rhs) -> bool

This method tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

This method tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

This method tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

This method tests greater than or equal to (for self and other) and is used by the >= operator.
