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 set_error(&self, e: impl Debug)

Set last_error field

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

pub fn clear_error(&self)

Unset last_error field

pub fn set_input(&mut self, input: *const u8, len: usize)

Store input in memory and initialize Internal pointer

pub fn dump_memory(&self)

pub fn reinstantiate(&mut self) -> Result<(), Error>

pub fn has_wasi(&self) -> bool

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.

impl Drop for Plugin

fn drop(&mut self)

Executes the destructor for this type.
