Struct wasmedge_sys::ImportModule

pub struct ImportModule { /* private fields */ }

An ImportModule represents a host module with a name. A host module consists of one or more host function, table, memory, and global instances, which are defined outside wasm modules and fed into wasm modules as imports.

Implementations

impl ImportModule

pub fn create(name: impl AsRef<str>) -> WasmEdgeResult<Self>

Creates a module instance which is used to import host functions, tables, memories, and globals into a wasm module.

Argument

• name - The name of the import module instance.

Error

If fail to create the import module instance, then an error is returned.

pub fn as_ptr(&self) -> *const WasmEdge_ModuleInstanceContext

Provides a raw pointer to the inner module instance context.
