Struct Instances 

pub struct Instances { /* private fields */ }

Map from canonical name to instantiated module.

Deduplicates the import graph within a single load_module and can act as a host-level cache across calls. Since a name fixes the frame and imports, cached instances remain valid unless dropped.

Implementations

impl Instances

pub fn new() -> Instances

Create an empty instance map.

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

Get the instance for name.

pub fn insert(&mut self, name: ModuleName, value: Value)

Insert or replace the instance for name.

pub fn len(&self) -> usize

Number of modules in the map.

pub fn is_empty(&self) -> bool

Whether the map is empty.

pub fn names(&self) -> impl Iterator<Item = &ModuleName>

Canonical names in insertion order.

Trait Implementations
