Struct wasmedge_sys::instance::module::ImportModule

pub struct ImportModule<T: ?Sized + Send + Sync + Clone> { /* 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<T: ?Sized + Send + Sync + Clone> ImportModule<T>

pub fn create( name: impl AsRef<str>, data: Option<Box<T>> ) -> 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.

• data - The host context data used in this function.

Error

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

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

Available on crate feature ffi only.

Provides a raw pointer to the inner module instance context.
