Struct linera_witty::wasmer::FunctionEnvMut

pub struct FunctionEnvMut<'a, T>
where
    T: 'a,
{ /* private fields */ }

A temporary handle to a FunctionEnv.

Implementations

impl<T> FunctionEnvMut<'_, T>

where T: 'static,

pub fn data(&self) -> &T

Returns a reference to the host state in this function environement.

pub fn data_mut(&mut self) -> &mut T

Returns a mutable- reference to the host state in this function environement.

pub fn as_ref(&self) -> FunctionEnv<T>

Borrows a new immmutable reference

pub fn as_mut(&mut self) -> FunctionEnvMut<'_, T>

Borrows a new mutable reference

pub fn data_and_store_mut(&mut self) -> (&mut T, StoreMut<'_>)
