Struct FunctionStore

pub struct FunctionStore<'a> { /* private fields */ }

A function store contains all of the functions that are accessible to an interpreter.

Implementations

impl<'a> FunctionStore<'a>

pub fn add(&mut self, name: String, function: &'a Function)

Add a function by name.

pub fn index_of(&self, name: &str) -> Option<FuncIndex>

Retrieve the index of a function in the function store by its name.

pub fn get_by_index(&self, index: FuncIndex) -> Option<&'a Function>

Retrieve a function by its index in the function store.

pub fn get_by_name(&self, name: &str) -> Option<&'a Function>

Retrieve a function by its name.

pub fn get_from_func_ref( &self, func_ref: FuncRef, function: &Function, ) -> Option<&'a Function>

Retrieve a function from a [FuncRef] within a [Function]. TODO this should be optimized, if possible, as currently it retrieves the function name as a string and performs string matching.

Trait Implementations

impl<'a> Clone for FunctionStore<'a>

fn clone(&self) -> FunctionStore<'a>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<'a> Default for FunctionStore<'a>

fn default() -> FunctionStore<'a>

Returns the “default value” for a type.

impl<'a> From<&'a Function> for FunctionStore<'a>

This is a helpful conversion for instantiating a store from a single [Function].

fn from(function: &'a Function) -> Self

Converts to this type from the input type.
