Struct Inspectable

Source 
pub struct Inspectable<V, W>
where
    W: Watch<V>,
{ /* private fields */ }
Expand description

Generic wrapper for exporting variables via Inspect. Mutations to the wrapped value occur through an InspectableGuard, which notifies the watcher when Dropped, transparently keeping the Inspect state up-to-date.

How the value is exported is determined by the Watch implementation, see e.g. InspectableDebugString.

Not correct for Vs with interior mutability, because Inspectable Derefs to V, mutations to which will bypass the watcher.

Implementations§

Source§

impl<V, W> Inspectable<V, W>
where W: Watch<V>,

Source

pub fn new(value: V, node: &Node, name: impl Into<StringReference>) -> Self

Creates an Inspectable wrapping value. Exports value via Inspect.

Source

pub fn get_mut(&mut self) -> InspectableGuard<'_, V, W>

Returns a guard that DerefMuts to the wrapped value. The watcher will receive the updated value when the guard is Dropped.
