Struct tor_config::MutCfg
source · [−]pub struct MutCfg<T> { /* private fields */ }
Expand description
A mutable configuration object.
Internally, this is just a RwLock<Arc<T>>
; this type just defines some
convenience wrappers for it.
Implementations

impl<T> MutCfg<T>
sourcepub fn check_and_replace(&self, old_config: &Arc<T>, new_config: T) -> bool
pub fn check_and_replace(&self, old_config: &Arc<T>, new_config: T) -> bool
If this configuration object is still the same pointer as old_config
,
replace it with new_config
.
Returns true
if it was in fact replaced.
sourcepub fn map_and_replace<F>(&self, func: F) where
F: FnOnce(&Arc<T>) -> T,
pub fn map_and_replace<F>(&self, func: F) where
F: FnOnce(&Arc<T>) -> T,
Replace the current configuration with the results of evaluating func
on it.
