Exports

Struct Exports 

Source
pub struct Exports { /* private fields */ }
Expand description

Exports is used to get exports like Funcs, DynFuncs, Memorys, Globals, and Tables from an Instance.

Use Instance.exports to get an Exports from an Instance.

Implementations§

Source§

impl Exports

Source

pub fn get<'a, T: Exportable<'a>>(&'a self, name: &str) -> ResolveResult<T>

Get an export.

// We can get a function as a static `Func`
let func: Func<i32, i32> = instance.exports.get("my_func")?;
let _result = func.call(42);

// Or we can get it as a dynamic `DynFunc`
let dyn_func: DynFunc = instance.exports.get("my_func")?;
let _result= dyn_func.call(&[Value::I32(42)]);

// We can also get other exports like `Global`s, `Memory`s, and `Table`s
let _counter: Global = instance.exports.get("counter")?;
Source

pub fn into_iter(&self) -> ExportIter<'_>

Iterate the exports.

for (export_name, export_value) in instance.exports.into_iter() {
   println!("Found export `{}` with value `{:?}`", export_name, export_value);
}
