Trait Implementations

impl ModuleInstanceInterface for ModuleInstance

fn instantiate<'a>(
    &self,
    is_user_module: bool,
    externals: Option<&'a HashMap<String, Arc<ModuleInstanceInterface + 'a>>>
) -> Result<(), Error>

Run instantiation-time procedures (validation and start function [if any] call). Module is not completely validated until this call.

fn execute_index(
    &self,
    index: u32,
    params: ExecutionParams
) -> Result<Option<RuntimeValue>, Error>

Execute function with the given index.

fn execute_export(
    &self,
    name: &str,
    params: ExecutionParams
) -> Result<Option<RuntimeValue>, Error>

Execute function with the given export name.

fn export_entry<'a>(
    &self,
    name: &str,
    externals: Option<&'a HashMap<String, Arc<ModuleInstanceInterface + 'a>>>,
    required_type: &ExportEntryType
) -> Result<Internal, Error>

Get export entry.

fn function_type<'a>(
    &self,
    function_index: ItemIndex,
    externals: Option<&'a HashMap<String, Arc<ModuleInstanceInterface + 'a>>>
) -> Result<FunctionType, Error>

Get function type.

fn table(&self, index: ItemIndex) -> Result<Arc<TableInstance>, Error>

Get table reference.

fn memory(&self, index: ItemIndex) -> Result<Arc<MemoryInstance>, Error>

Get memory reference.

fn global(
    &self,
    index: ItemIndex,
    variable_type: Option<VariableType>
) -> Result<Arc<VariableInstance>, Error>

Get global reference.

fn call_function(
    &self,
    outer: CallerContext,
    index: ItemIndex,
    function_type: Option<&FunctionType>
) -> Result<Option<RuntimeValue>, Error>

Call function with given index in functions index space.

fn call_function_indirect(
    &self,
    outer: CallerContext,
    table_index: ItemIndex,
    type_index: u32,
    func_index: u32
) -> Result<Option<RuntimeValue>, Error>

Call function with given index in the given table.

fn call_internal_function(
    &self,
    outer: CallerContext,
    index: u32,
    function_type: Option<&FunctionType>
) -> Result<Option<RuntimeValue>, Error>

Call function with internal index.
