The thread-local callback context for #[trace]
.
Methods
impl Context
[src]
pub fn default_callback(ctx: &mut Context, event: Event)
[src]
The default callback registered by Self::new()
.
pub fn stack(&self) -> &[CallContext]
[src]
Returns the current call stack.
pub fn top(&self) -> &CallContext
[src]
Returns the top of the current call stack.
pub fn register_callback<F, G>(&mut self, f: F) where
F: FnOnce(Option<Callback>) -> G,
G: Fn(&mut Context, Event) + 'static,
[src]
F: FnOnce(Option<Callback>) -> G,
G: Fn(&mut Context, Event) + 'static,
Registers a callback. A previously registered callback is passed to the outer closure.
pub fn unregister_callback(&mut self) -> Option<Callback>
[src]
Unregisters a callback.
