Trait Implementations

impl Clone for Metadata

fn clone(&self) -> Metadata

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Metadata

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Metadata

fn deserialize<__D>( __deserializer: __D, ) -> Result<Metadata, <__D as Deserializer<'de>>::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for Metadata

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

Formats the value using the given formatter.

impl From<<Metadata as OperationReflect>::OpCode> for OpCode

fn from(value: <Metadata as OperationReflect>::OpCode) -> OpCode

Converts to this type from the input type.

impl From<Metadata> for Operation

fn from(value: Metadata) -> Operation

Converts to this type from the input type.

impl Hash for Metadata

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 OperationReflect for Metadata

type OpCode = MetadataOpCode

Type of the op codes for this operation

fn op_code(&self) -> <Metadata as OperationReflect>::OpCode

Get the opcode for this operation

fn args(&self) -> Option<Vec<Variable>>

Get the list of arguments for this operation. If not all arguments are Variable, returns None instead.

fn from_code_and_args( op_code: <Metadata as OperationReflect>::OpCode, args: &[Variable], ) -> Option<Metadata>

Create typed operation from an opcode and a list of arguments. Returns None if not all arguments are Variable.

fn is_commutative(&self) -> bool

Whether this operation is commutative (arguments can be freely reordered). Ignored for single argument operations.

fn is_pure(&self) -> bool

Whether this operation is pure (has no side effects). Things like uniform/plane operations are considered impure, because they affect other units.

impl PartialEq for Metadata

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

Tests for self and other values to be equal, and is used by ==.

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

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

impl Serialize for Metadata

fn serialize<__S>( &self, __serializer: __S, ) -> Result<<__S as Serializer>::Ok, <__S as Serializer>::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl TypeHash for Metadata

fn write_hash(hasher: &mut impl Hasher)

Write the structure of the type to the hasher

fn type_hash() -> u64

Generate a stable hash of the type structure.

impl Eq for Metadata

impl StructuralPartialEq for Metadata
