Struct ConfigHandle 

pub struct ConfigHandle<T: Send + Sync + 'static> { /* private fields */ }

A shared handle to a configuration value.

ConfigHandle<T> wraps an Arc<ArcSwap<T>> to provide:

• load(): Read the current configuration snapshot (returns Arc<T>).
• set(): Update the configuration value.
• clone: Share the same underlying swap cell across multiple handles.

Multiple ConfigHandle<T> clones point to the same underlying swap cell. Updates via one handle are immediately visible to all other handles.

Old snapshots (returned by load()) remain valid after updates.

Type Constraints

T must satisfy Send + Sync + 'static and Sized.

Example

use trait_kit::core::config::ConfigHandle;

let handle = ConfigHandle::new(42);
assert_eq!(*handle.load(), 42);

let cloned = handle.clone();
handle.set(100);
assert_eq!(*cloned.load(), 100);

Implementations

impl<T: Send + Sync + 'static> ConfigHandle<T>

pub fn new(value: T) -> Self

Create a new ConfigHandle with an initial value.

pub fn load(&self) -> Arc<T>

Load the current configuration snapshot.

Returns an Arc<T> that remains valid even after subsequent set() calls.

pub fn set(&self, value: T)

Update the configuration value.

All clones of this handle will see the new value on their next load() call.

Trait Implementations

impl<T: Send + Sync + 'static> Clone for ConfigHandle<T>

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<T: Debug + Send + Sync + 'static> Debug for ConfigHandle<T>

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

Formats the value using the given formatter.
