Struct ArcMutexKeyPathChain 

pub struct ArcMutexKeyPathChain<Root, MutexValue, InnerValue, SubValue, F, G>
where
    F: for<'r> Fn(&'r Root) -> &'r MutexValue,
    G: for<'r> Fn(&'r InnerValue) -> &'r SubValue,
{ /* private fields */ }

A composed keypath chain through Arc<Mutex> - functional style Build the chain first, then apply container at get() time

Example

// Functional style: compose first, then apply container at get()
ContainerTest::mutex_data_r()
    .then_arc_mutex_at_kp(SomeStruct::data_r())
    .get(&container, |value| println!("Value: {}", value));

Implementations

impl<Root, MutexValue, InnerValue, SubValue, F, G> ArcMutexKeyPathChain<Root, MutexValue, InnerValue, SubValue, F, G>

where F: for<'r> Fn(&'r Root) -> &'r MutexValue, G: for<'r> Fn(&'r InnerValue) -> &'r SubValue, MutexValue: Borrow<Arc<Mutex<InnerValue>>>,

pub fn get<Callback>(self, container: &Root, callback: Callback) -> Option<()>

where Callback: FnOnce(&SubValue),

Apply the composed keypath chain to a container, executing callback with the value (read) Consumes self - functional style (compose once, apply once)
