Struct ArcRwLockOptionalKeyPathChain 

Source 
pub struct ArcRwLockOptionalKeyPathChain<Root, RwLockValue, InnerValue, SubValue, F, G>
where
    F: for<'r> Fn(&'r Root) -> &'r RwLockValue,
    G: for<'r> Fn(&'r InnerValue) -> Option<&'r SubValue>,
{ /* private fields */ }
Expand description

A composed optional keypath chain through Arc<RwLock> - functional style

Implementations§

Source§

impl<Root, RwLockValue, InnerValue, SubValue, F, G> ArcRwLockOptionalKeyPathChain<Root, RwLockValue, InnerValue, SubValue, F, G>
where F: for<'r> Fn(&'r Root) -> &'r RwLockValue, G: for<'r> Fn(&'r InnerValue) -> Option<&'r SubValue>, RwLockValue: Borrow<Arc<RwLock<InnerValue>>>,

Source

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 lock) Consumes self - functional style (compose once, apply once)
