Struct wasmer_runtime_core::import::ImportObject

pub struct ImportObject { /* fields omitted */ }

All of the import data used when instantiating.

It's suggested that you use the imports! macro instead of creating an ImportObject by hand.

Usage:

let import_object = imports! {
    "env" => {
        "foo" => func!(foo),
    },
};

fn foo(_: &mut Ctx, n: i32) -> i32 {
    n
}

Methods

impl ImportObject

pub fn new() -> Self

Create a new ImportObject.

pub fn register<S, N>(
    &mut self,
    name: S,
    namespace: N
) -> Option<Box<dyn LikeNamespace>> where
    S: Into<String>,
    N: LikeNamespace + 'static, 

Register anything that implements LikeNamespace as a namespace.

Usage:

fn register(instance: Instance, namespace: Namespace) {
    let mut import_object = ImportObject::new();

    import_object.register("namespace0", instance);
    import_object.register("namespace1", namespace);
    // ...
}

pub fn get_namespace(
    &self,
    namespace: &str
) -> Option<&(dyn LikeNamespace + 'static)>
