Struct tracing_fmt::filter::reload::Handle

pub struct Handle<F, N> where
    F: Filter<N>,  { /* fields omitted */ }

Methods

impl<F, N> Handle<F, N> where
    F: Filter<N> + 'static, 

pub fn reload(&self, new_filter: impl Into<F>) -> Result<(), Error>

pub fn modify(&self, f: impl FnOnce(&mut F)) -> Result<(), Error>

Invokes a closure with a mutable reference to the current filter, allowing it to be modified in place.

pub fn clone_current(&self) -> Option<F> where
    F: Clone, 

Returns a clone of the filter's current value if it still exists. Otherwise, if the filter has been dropped, returns None.

pub fn with_current<T>(&self, f: impl FnOnce(&F) -> T) -> Result<T, Error>

Invokes a closure with a borrowed reference to the current filter, returning the result (or an error if the filter no longer exists).
