Enum PrattResult 

pub enum PrattResult {
    ExprInfix,
    ExprPrefix,
    ExprPostfix,
    Call(Symbol),
    Custom(Symbol),
}

The expression form a matched PrattOperator produces.

Variants

ExprInfix

Build a binary expression from the operator and its two operands.

ExprPrefix

Build a unary expression from the operator and its trailing operand.

ExprPostfix

Build a unary expression from the operator and its leading operand.

Call(Symbol)

Emit a call to the named callable with the operands as arguments.

Custom(Symbol)

Emit a custom form keyed by the given symbol for the grammar to interpret.

Trait Implementations

impl Clone for PrattResult

fn clone(&self) -> PrattResult

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for PrattResult

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

Formats the value using the given formatter.

impl Eq for PrattResult

impl PartialEq for PrattResult

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