Type Alias ReentrantInstance 

pub type ReentrantInstance<'a, UserData> = Caller<'a, UserData>;

Alias for the Instance implementation made available inside host functions called by the guest.

Aliased Type

pub struct ReentrantInstance<'a, UserData> { /* private fields */ }

Trait Implementations

impl<Parameters, Results, UserData> InstanceWithFunction<Parameters, Results> for ReentrantInstance<'_, UserData>

where Parameters: FlatLayout + WasmtimeParameters, Results: FlatLayout + WasmtimeResults,

type Function = TypedFunc<<Parameters as WasmtimeParameters>::Parameters, <Results as WasmtimeResults>::Results>

The runtime-specific type to represent the function.

fn function_from_export( &mut self, export: <Self::Runtime as Runtime>::Export, ) -> Result<Option<Self::Function>, RuntimeError>

Converts an export into a function, if it is one.

fn call( &mut self, function: &Self::Function, parameters: Parameters, ) -> Result<Results, RuntimeError>

Calls the function from this instance using the specified parameters.

fn load_function(&mut self, name: &str) -> Result<Self::Function, RuntimeError>

Loads a function from the guest Wasm instance.

impl<UserData> InstanceWithMemory for ReentrantInstance<'_, UserData>

fn memory_from_export( &self, export: Extern, ) -> Result<Option<Memory>, RuntimeError>

Converts an export into the runtime’s specific memory type.

fn memory(&mut self) -> Result<Memory<'_, Self>, RuntimeError>

Returns the memory export from the current Wasm module instance.

fn load_memory( &mut self, ) -> Result<<Self::Runtime as Runtime>::Memory, RuntimeError>

Resolves the guest module’s memory export.
