Struct wasmedge_sdk::Instance

pub struct Instance { /* private fields */ }

Represents an instantiated module.

An Instance represents an instantiated module. In the instantiation process, A module instance is created based on a compiled module. From a [module instance] the exported host function, table, memory, and global instances can be fetched.

Implementations

impl Instance

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

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

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

pub fn func(&self, name: impl AsRef<str>) -> WasmEdgeResult<Func>

Returns the exported function instance in this module instance by the given function name.

Argument

• name - the name of the target exported function instance.

pub fn global_count(&self) -> usize

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

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

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

pub fn global(&self, name: impl AsRef<str>) -> WasmEdgeResult<Global>

Returns the exported global instance in this module instance by the given global name.

Argument

• name - the name of the target exported global instance.

pub fn memory_count(&self) -> usize

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

pub fn memory_names(&self) -> Option<Vec<String>>

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

pub fn memory(&self, name: impl AsRef<str>) -> WasmEdgeResult<Memory>

Returns the exported memory instance in this module instance by the given memory name.

Argument

pub fn table_count(&self) -> usize

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

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

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

pub fn table(&self, name: impl AsRef<str>) -> WasmEdgeResult<Table>

Returns the exported table instance in this module instance by the given table name.

Argument

• name - the name of the target exported table instance.

pub fn host_data<T: Send + Sync + Clone>(&mut self) -> Option<&mut T>

Returns the host data held by the module instance.

Trait Implementations

impl Clone for Instance
