Struct tracing_subscriber::reload::Handle
source · pub struct Handle<L, S> { /* private fields */ }
Expand description
Allows reloading the state of an associated Layer
.
Implementations§
source§impl<L, S> Handle<L, S>where
L: Layer<S> + 'static,
S: Subscriber,
impl<L, S> Handle<L, S>where L: Layer<S> + 'static, S: Subscriber,
sourcepub fn reload(&self, new_layer: impl Into<L>) -> Result<(), Error>
pub fn reload(&self, new_layer: impl Into<L>) -> Result<(), Error>
Replace the current layer with the provided new_layer
.
sourcepub fn modify(&self, f: impl FnOnce(&mut L)) -> Result<(), Error>
pub fn modify(&self, f: impl FnOnce(&mut L)) -> Result<(), Error>
Invokes a closure with a mutable reference to the current layer, allowing it to be modified in place.
sourcepub fn clone_current(&self) -> Option<L>where
L: Clone,
pub fn clone_current(&self) -> Option<L>where L: Clone,
Returns a clone of the layer’s current value if it still exists.
Otherwise, if the subscriber has been dropped, returns None
.
