Method get_export_index

crates/wasmtime/src/runtime/module.rs:895–904

Looks up an export in this [`Module`] by name to get its index. This function will return the index of an export with the given name. This can be useful to avoid the cost of looking up the export by name multiple times. Instead the [`ModuleExport`] can be stored and used to look up the export on the [`Instance`](crate::Instance) later.
