Struct wasmer::FunctionEnv

#[repr(transparent)]
pub struct FunctionEnv<T> {
    pub(crate) handle: StoreHandle<VMFunctionEnvironment>,
    marker: PhantomData<T>,
}

An opaque reference to a function environment. The function environment data is owned by the Store.

Fields

handle: StoreHandle<VMFunctionEnvironment>

marker: PhantomData<T>

Implementations

impl<T> FunctionEnv<T>

pub fn new(store: &mut impl AsStoreMut, value: T) -> Selfwhere T: Any + Send + 'static + Sized,

Make a new FunctionEnv

pub fn as_ref<'a>(&self, store: &'a impl AsStoreRef) -> &'a Twhere T: Any + Send + 'static + Sized,

Get the data as reference

pub(crate) fn from_handle(handle: StoreHandle<VMFunctionEnvironment>) -> Self

pub fn as_mut<'a>(&self, store: &'a mut impl AsStoreMut) -> &'a mut Twhere T: Any + Send + 'static + Sized,

Get the data as mutable

pub fn into_mut(self, store: &mut impl AsStoreMut) -> FunctionEnvMut<'_, T>where T: Any + Send + 'static + Sized,

Convert it into a FunctionEnvMut

Trait Implementations

impl<T> Clone for FunctionEnv<T>

fn clone(&self) -> Self

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<T: Debug> Debug for FunctionEnv<T>

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

Formats the value using the given formatter.

impl<T> Hash for FunctionEnv<T>

fn hash<H: Hasher>(&self, state: &mut H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl<T> PartialEq<FunctionEnv<T>> for FunctionEnv<T>

fn eq(&self, other: &Self) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
