Enum wasmtime_environ::component::InstantiateModule

pub enum InstantiateModule {
    Static(StaticModuleIndex, Box<[CoreDef]>),
    Import(RuntimeImportIndex, IndexMap<String, IndexMap<String, CoreDef>>),
}

Different methods of instantiating a core wasm module.

Variants

Static(StaticModuleIndex, Box<[CoreDef]>)

A module defined within this component is being instantiated.

Note that this is distinct from the case of imported modules because the order of imports required is statically known and can be pre-calculated to avoid string lookups related to names at runtime, represented by the flat list of arguments here.

Import(RuntimeImportIndex, IndexMap<String, IndexMap<String, CoreDef>>)

An imported module is being instantiated.

This is similar to Upvar but notably the imports are provided as a two-level named map since import resolution order needs to happen at runtime.
