# [−] [src] Struct wasmi::NotStartedModuleRef

    pub struct NotStartedModuleRef<'a> { /* fields omitted */ }

Mostly instantiated `ModuleRef`.

At this point memory segments and tables are copied. However, `start` function (if any) is not called. To get fully instantiated module instance, running `start` function is required.

You can still access not fully initialized instance by calling `not_started_instance`, but keep in mind, that this is sort of escape hatch: module really might depend on initialization done in `start` function. It's definitely not recommended to call any exports on `ModuleRef` returned by this function.

If you sure, that there is no `start` function (e.g. because you created it without one), you can call `assert_no_start` which returns `ModuleRef` without calling `start` function. However, it will panic if module contains `start` function.

## Methods

### `impl<'a> NotStartedModuleRef<'a>` [src]

#### `pub fn not_started_instance(&self) -> &ModuleRef` [src]

Returns not fully initialized instance.

To fully initialize the instance you need to call either `run_start` or `assert_no_start`. See struct documentation for details.

#### `pub fn run_start<E: Externals>(self, state: &mut E) -> Result<ModuleRef, Trap>` [src]

Executes `start` function (if any) and returns fully instantiated module.

# Errors

Returns `Err` if start function traps.

#### `pub fn assert_no_start(self) -> ModuleRef` [src]

Returns fully instantiated module without running `start` function.

# Panics

This function panics if original module contains `start` function.

#### `pub fn has_start(&self) -> bool` [src]

Whether or not the module has a `start` function.

Returns `true` if it has a `start` function.

## Search Tricks

Prefix searches with a type followed by a colon (e.g., `fn:`) to restrict the search to a given type.

Accepted types are: `fn`, `mod`, `struct`, `enum`, `trait`, `type`, `macro`, and `const`.

Search functions by type signature (e.g., `vec -> usize` or `* -> vec`)

Search multiple things at once by splitting your query with comma (e.g., `str,u8` or `String,struct:Vec,test`)
