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§

source§

impl<T> MutCfg<T>

source

pub fn new(config: T) -> Self

Return a new MutCfg with the provided value.

source

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

Return the current configuration

source

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.

source

pub fn replace(&self, new_config: T)

Replace this configuration with new_config.

source

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.
