}
Expand description

Import resolver connects imports with available exported values.

Required Methods

Resolves an import a WebAssembly module to an export it’s hooked up to.

The index provided is the index of the import in the wasm module that’s being resolved. For example 1 means that it’s the second import listed in the wasm module.

The module and field arguments provided are the module/field names listed on the import itself.

Notes:

The index is useful because some WebAssembly modules may rely on that for resolving ambiguity in their imports. Such as:

ⓘ
(module
  (import "" "" (func))
  (import "" "" (func (param i32) (result i32)))
)
