Implementations

impl Plugin

pub fn new(wasm: impl AsRef<[u8]>, 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 set_error(&mut self, e: impl Debug)

Set last_error field

pub fn error<E>(&mut self, e: impl Debug, x: E) -> E

pub fn clear_error(&mut self)

Unset last_error field

pub fn set_input(&mut self, handle: MemoryBlock)

Store input in memory and initialize Internal pointer

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.
