Struct Controller 

pub struct Controller { /* private fields */ }

Per-execution controller. Not thread-safe - create one per concurrent call. Lightweight, created from Runtime. Each controller has its own isolated Store and Instance.

Implementations

impl Controller

pub async fn alloc(&mut self, len: u32) -> Result<u32>

pub async fn free(&mut self, ptr: u32, len: u32) -> Result<()>

pub async fn init(&mut self) -> Result<()>

pub async fn invoke<A: Args>( &mut self, name: Option<String>, args: A, ) -> Result<Value>

pub async fn args(&mut self, name: Option<String>) -> Result<Vec<Kind>>

pub async fn returns(&mut self, name: Option<String>) -> Result<Kind>

pub fn list(&mut self) -> Result<Vec<String>>

Trait Implementations

impl AsyncMemoryController for Controller

fn alloc<'life0, 'async_trait>( &'life0 mut self, len: u32, ) -> Pin<Box<dyn Future<Output = Result<u32>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait,

Allocate a region of WASM linear memory (async).

fn free<'life0, 'async_trait>( &'life0 mut self, ptr: u32, len: u32, ) -> Pin<Box<dyn Future<Output = Result<()>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait,

Free a previously allocated region of memory (async).

fn mut_mem(&mut self, ptr: u32, len: u32) -> Result<&mut [u8]>

Get mutable access to a region of WASM linear memory.

impl Debug for Controller

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
