Expand description

The object as an module instance is required to implement this trait.

Required Methods§

Source

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

§Safety

Provides a raw pointer to the inner module instance context. The lifetime of the returned pointer must not exceed that of the object itself.

Provided Methods§

Source

fn name(&self) -> Option<String>

Returns the name of this exported module instance.

If this module instance is an active module instance, then None is returned.

Source

fn get_table( &self, name: impl AsRef<str>, ) -> Result<InnerRef<Table, &Self>, Box<WasmEdgeError>>
where Self: Sized,

Returns the exported table instance by name.

§Argument
§Error

If fail to find the target table instance, then an error is returned.

Source

fn get_memory_ref( &self, name: impl AsRef<str>, ) -> Result<InnerRef<Memory, &Self>, Box<WasmEdgeError>>
where Self: Sized,

Returns the exported memory instance by name.

§Argument
§Error

If fail to find the target memory instance, then an error is returned.

Source

fn get_memory_mut( &mut self, name: impl AsRef<str>, ) -> Result<InnerRef<Memory, &mut Self>, Box<WasmEdgeError>>
where Self: Sized,

Source

fn get_global( &self, name: impl AsRef<str>, ) -> Result<InnerRef<Global, &Self>, Box<WasmEdgeError>>
where Self: Sized,

Returns the exported global instance by name.

§Argument
§Error

If fail to find the target global instance, then an error is returned.

Source

fn get_global_mut( &mut self, name: impl AsRef<str>, ) -> Result<InnerRef<Global, &mut Self>, Box<WasmEdgeError>>
where Self: Sized,

Source

fn func_len(&self) -> u32

Returns the length of the exported function instances in this module instance.

Source

fn func_names(&self) -> Option<Vec<String>>

Returns the names of the exported function instances in this module instance.

Source

fn get_func( &self, name: &str, ) -> Result<InnerRef<Function, &Instance>, Box<WasmEdgeError>>

Returns the exported function instance by name.

§Argument
§Error

If fail to find the target function, then an error is returned.

Source

fn get_func_mut( &mut self, name: &str, ) -> Result<InnerRef<Function, &mut Instance>, Box<WasmEdgeError>>

Returns the exported function instance by name.

§Argument
§Error

If fail to find the target function, then an error is returned.

Source

fn table_len(&self) -> u32

Returns the length of the exported table instances in this module instance.

Source

fn table_names(&self) -> Option<Vec<String>>

Returns the names of the exported table instances in this module instance.

Source

fn mem_len(&self) -> u32

Returns the length of the exported memory instances in this module instance.

Source

fn mem_names(&self) -> Option<Vec<String>>

Returns the names of all exported memory instances in this module instance.

Source

fn global_len(&self) -> u32

Returns the length of the exported global instances in this module instance.

Source

fn global_names(&self) -> Option<Vec<String>>

Returns the names of the exported global instances in this module instance.
