Struct AtomMap 

Source 
pub struct AtomMap<'a, T: Send + Sync + 'static, R, F> { /* private fields */ }
Expand description

A projected view into an Atom<T>, created by Atom::map().

Loading from an AtomMap loads the full T and applies the projection function to return a reference to a sub-field.

Implementations§

Source§

impl<'a, T: Send + Sync + 'static, R, F> AtomMap<'a, T, R, F>
where F: Fn(&T) -> &R,

Source

pub fn load(&self) -> AtomMapGuard<'a, T, R, F>

Load the projected value.

Internally loads the full T and applies the projection.
