Plugin contains everything needed to execute a WASM function

Fields

modules: BTreeMap<String, Module>

All modules that were provided to the linker

linker: Linker<Internal>

Used to define functions and create new instances

store: Store<Internal>

instance: Option<Instance>

Instance provides the ability to call functions in a module

instance_pre: InstancePre<Internal>

timer_id: Uuid

The ID used to identify this plugin with the Timer

Implementations

impl Plugin

pub fn new<'a>( wasm: impl AsRef<[u8]>, imports: impl IntoIterator<Item = &'a Function>, with_wasi: bool ) -> Result<Plugin, Error>

Create a new plugin from the given WASM code

pub fn get_func(&mut self, function: impl AsRef<str>) -> Option<Func>

Get a function by name

pub fn has_wasi(&self) -> bool

Determine if wasi is enabled

Trait Implementations

impl<'a> AsMut<Plugin> for PluginRef<'a>

fn as_mut(&mut self) -> &mut Plugin

Converts this type into a mutable reference of the (usually inferred) input type.

impl<'a> AsRef<Plugin> for PluginRef<'a>

fn as_ref(&self) -> &Plugin

Converts this type into a shared reference of the (usually inferred) input type.
