Implementations

impl<'b> RuntimeInstance<'b, EmptyHookSet>

pub fn new(validation_info: &ValidationInfo<'b>) -> CustomResult<Self>

pub fn new_named( module_name: &str, validation_info: &ValidationInfo<'b>, ) -> CustomResult<Self>

impl<'b, H> RuntimeInstance<'b, H>

where H: HookSet + Debug,

pub fn add_module( &mut self, module_name: &str, validation_info: &ValidationInfo<'b>, ) -> CustomResult<()>

pub fn new_with_hooks( module_name: &str, validation_info: &ValidationInfo<'b>, hook_set: H, ) -> CustomResult<Self>

pub fn get_function_by_name( &self, module_name: &str, function_name: &str, ) -> Result<FunctionRef, RuntimeError>

pub fn get_function_by_index( &self, module_addr: usize, function_idx: usize, ) -> Result<FunctionRef, RuntimeError>

pub fn invoke<Param: InteropValueList, Returns: InteropValueList>( &mut self, function_ref: &FunctionRef, params: Param, ) -> Result<Returns, RuntimeError>

pub fn invoke_dynamic( &mut self, function_ref: &FunctionRef, params: Vec<Value>, ret_types: &[ValType], ) -> Result<Vec<Value>, RuntimeError>

Invokes a function with the given parameters, and return types which are not known at compile time.

pub fn invoke_dynamic_unchecked_return_ty( &mut self, function_ref: &FunctionRef, params: Vec<Value>, ) -> Result<Vec<Value>, RuntimeError>

Get the indicies of a module and function by their names.

Arguments

• module_name: The module in which to find the function.
• function_name: The name of the function to find inside the module. The function must be a local function and not an import.

Returns

• Ok((module_idx, func_idx)), where module_idx is the internal index of the module inside the RuntimeInstance, and func_idx is the internal index of the function inside the module.
• Err(RuntimeError::ModuleNotFound), if the module is not found.
• Err(RuntimeError::FunctionNotFound, if the function is not found within the module.
