Trait Implementations

impl Clone for PrefixOp

fn clone(&self) -> PrefixOp

Returns a copy of the value.

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

Performs copy-assignment from source.

impl PartialEq<PrefixOp> for PrefixOp

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

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

#[must_use]

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

This method tests for !=.

impl Copy for PrefixOp

impl Display for PrefixOp

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

Formats the value using the given formatter.

impl Debug for PrefixOp

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

Formats the value using the given formatter.

impl InferTypesUnary for PrefixOp

type Operand = PType

The Type object being used as the operand.

fn infer_types(&self, operand: PType) -> Option<UnaryOpTypes<PType>>

When the operation is posssible, returns Some(...) containing the required operand coercions and the result type. When the operation is not possible with the given operand type, return None.

impl UnaryOperator<PType, Value> for PrefixOp

fn op(&self, ty: PType, operand: &Value) -> Result<Value, String>

Performs the oepration with the operand operand, with outpu type ty.type
