pub struct WasiEnv {
    pub state: Arc<WasiState>,
    /* private fields */
}

The environment provided to the WASI imports.

Fields

state: Arc<WasiState>

Shared state of the WASI system. Manages all the data that the executing WASI program can see.

Implementations

impl WasiEnv

pub fn new(state: WasiState) -> Self

Create a new WasiEnv from a WasiState (memory will be set to None)

pub fn runtime(&self) -> &dyn WasiRuntimeImplementation

Returns a copy of the current runtime implementation for this environment

pub fn set_runtime<R>(&mut self, runtime: R)

where R: WasiRuntimeImplementation + Send + Sync + 'static,

Overrides the runtime implementation for this environment

pub fn current_thread_id(&self) -> WasiThreadId

Returns the current thread ID

pub fn new_thread(&self) -> WasiThread

Creates a new thread only this wasi environment

pub fn memory_clone(&self) -> Option<Memory>

pub fn set_memory(&mut self, memory: Memory)

Set the memory of the WasiEnv (can only be done once)

pub fn memory_view<'a>(&'a self, store: &'a impl AsStoreRef) -> MemoryView<'a>

Providers safe access to the memory (it must be initialized before it can be used)

pub fn memory(&self) -> &Memory

Get memory, that needs to have been set fist

pub fn state(&self) -> &WasiState

Get the WASI state
