Struct cushy::value::DynamicGuard

pub struct DynamicGuard<'a, T, const READONLY: bool = false> { /* private fields */ }

An exclusive reference to the contents of a Dynamic.

If the contents are accessed through DerefMut, all obververs will be notified of a change when this guard is dropped.

Implementations

impl<T, const READONLY: bool> DynamicGuard<'_, T, READONLY>

pub fn generation(&self) -> Generation

Returns the generation of the value at the time of locking the dynamic.

Even if this guard accesses the data through DerefMut, this value will remain unchanged while the guard is held.

pub fn prevent_notifications(&mut self)

Prevent any access through DerefMut from triggering change notifications.

pub fn unlocked<F, R>(&mut self, while_unlocked: F) -> R

where F: FnOnce() -> R,

Executes while_unlocked while this guard is temporarily unlocked.
