Struct RustdvShared 

pub struct RustdvShared<T> { /* private fields */ }

A handle to state shared between a component and its analysis port.

Cloning gives another handle to the same state, the way Rc does — it does not copy the data.

Implementations

impl<T> RustdvShared<T>

pub fn new(value: T) -> RustdvShared<T>

pub fn get(&self) -> Ref<'_, T>

Read the shared state.

The guard borrows at run time, so holding one across a call that also reads is fine and holding one across a call that writes panics. Keep the guard short — usually one line, as in let seen = self.tally.get();.

pub fn get_mut(&self) -> RefMut<'_, T>

Modify the shared state.

pub fn handle_count(&self) -> usize

How many handles point at this state — the component’s, the port’s, and any others.
