Struct darklua_core::process::Evaluator

pub struct Evaluator { /* private fields */ }

A struct to convert an Expression node into a LuaValue object.

Implementations

impl Evaluator

pub fn assume_pure_metamethods(self) -> Self

When evaluating expressions related to tables, this value tells the evaluator if metamethods can have side effects. For example, indexing a normal table in Lua does not have any side effects, but if the table is a metatable, it’s __index metamethod can possibly have side effects (since it can be a function call).

pub fn evaluate(&self, expression: &Expression) -> LuaValue

pub fn can_return_multiple_values(&self, expression: &Expression) -> bool

pub fn has_side_effects(&self, expression: &Expression) -> bool

Trait Implementations

impl Clone for Evaluator

fn clone(&self) -> Evaluator

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Evaluator

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

Formats the value using the given formatter.

impl Default for Evaluator

fn default() -> Evaluator

Returns the “default value” for a type.

impl PartialEq<Evaluator> for Evaluator

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