fn clone(&self) -> IsInstruction<N, VARIANT>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<N: Network, const VARIANT: u8> Debug for IsInstruction<N, VARIANT>

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

Prints the operation as a string.

impl<N: Network, const VARIANT: u8> Display for IsInstruction<N, VARIANT>

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

Prints the operation to a string.

impl<N: Network> From<IsInstruction<N, { Variant::IsEq as u8 }>> for Instruction<N>

fn from(operation: IsEq<N>) -> Self

Converts to this type from the input type.

impl<N: Network> From<IsInstruction<N, { Variant::IsNeq as u8 }>> for Instruction<N>

fn from(operation: IsNeq<N>) -> Self

Converts to this type from the input type.

impl<N: Network, const VARIANT: u8> FromBytes for IsInstruction<N, VARIANT>

fn read_le<R: Read>(reader: R) -> IoResult<Self>

Reads the operation from a buffer.

fn from_bytes_le(bytes: &[u8]) -> Result<Self, Error>where Self: Sized,

Returns Self from a byte array in little-endian order.

impl<N: Network, const VARIANT: u8> FromStr for IsInstruction<N, VARIANT>

fn from_str(string: &str) -> Result<Self>

Parses a string into an operation.

type Err = Error

The associated error which can be returned from parsing.

impl<N: Hash + Network, const VARIANT: u8> Hash for IsInstruction<N, VARIANT>

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

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<N: Network, const VARIANT: u8> Parser for IsInstruction<N, VARIANT>

fn parse(string: &str) -> ParserResult<'_, Self>

Parses a string into an operation.

impl<N: PartialEq + Network, const VARIANT: u8> PartialEq for IsInstruction<N, VARIANT>

fn eq(&self, other: &IsInstruction<N, VARIANT>) -> 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.
