Enum fr::compile::Eval

pub enum Eval {
    Load(Load),
    Literal(Literal),
    Call(Call),
    Deref(Deref),
    Refer(Refer),
    Value(Value),
}

This represents a value that can be evaluated. Variables, literals, function calls, value dereferences, variable references, and values (this is a cheat for letting the compiler easily use values in place of long Evals) can all be evaluated into a Value

Trait Implementations

impl Clone for Eval

fn clone(&self) -> Eval

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Eval

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

Formats the value using the given formatter.

impl Lower for Eval

An Eval expression is evaluated by the expression it contains

fn lower(&self) -> Result<Value, Error>

impl PartialEq<Eval> for Eval

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

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

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

This method tests for !=.

impl PartialOrd<Eval> for Eval

fn partial_cmp(&self, other: &Eval) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Eval) -> bool

This method tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Eval) -> bool

This method tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Eval) -> bool

This method tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Eval) -> bool

This method tests greater than or equal to (for self and other) and is used by the >= operator.
