Struct Module 

pub struct Module {
    pub path: Arc<str>,
    pub exports: HashSet<Arc<str>>,
    pub bindings: HashMap<Arc<str>, Value>,
}

One module’s contribution to the global symbol table: every binding it defines, plus the subset that’s been (provide)-d as exported.

Fields

path: Arc<str>

exports: HashSet<Arc<str>>

bindings: HashMap<Arc<str>, Value>

Implementations

impl Module

pub fn new(path: impl Into<Arc<str>>) -> Self

pub fn get_export(&self, name: &str) -> Option<Value>

Look up an exported binding. None if the name isn’t defined or isn’t in the export set.

pub fn add_export(&mut self, name: impl Into<Arc<str>>)

Add to the export set. Idempotent.

pub fn define(&mut self, name: impl Into<Arc<str>>, value: Value)

Bind a value (either from a define while loading or from embedder pre-population).

Trait Implementations

impl Clone for Module

fn clone(&self) -> Module

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Module

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

Formats the value using the given formatter.

impl Default for Module

fn default() -> Module

Returns the “default value” for a type.
