Trait Implementations

impl Clone for Alu

fn clone(&self) -> Alu

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Alu

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

Formats the value using the given formatter.

impl From<Alu> for Constraint

fn from(subgroup: Alu) -> Constraint

Converts to this type from the input type.

impl Hash for Alu

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 Alu

fn cmp(&self, other: &Alu) -> 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 Alu

fn eq(&self, other: &Alu) -> 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.

impl PartialOrd for Alu

fn partial_cmp(&self, other: &Alu) -> 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.

impl ToBytes for Alu

type Bytes = Alu

The iterator yielding bytes.

fn to_bytes(&self) -> <Alu as ToBytes>::Bytes

Convert the operation to its serialized form in bytes.

impl ToOpcode for Alu

type Opcode = Alu

The associated Opcode type.

fn to_opcode(&self) -> <Alu as ToOpcode>::Opcode

The opcode associated with this operation.

impl TryFromBytes for Alu

type Error = FromBytesError

Represents any error that might occur while parsing an op from bytes.

fn try_from_bytes( bytes: &mut impl Iterator<Item = u8>, ) -> Option<Result<Alu, <Alu as TryFromBytes>::Error>>

Parse a single operation from the given iterator yielding bytes.

impl Copy for Alu

impl Eq for Alu

impl StructuralPartialEq for Alu
