Trait RefKpTrait 

pub trait RefKpTrait<R, V>: KpTrait<R, V, &'static R, &'static V, &'static mut R, &'static mut V>
where
    R: 'static,
    V: 'static,
{
    // Required methods
    fn focus<'a>(&self, root: &'a R) -> Option<&'a V>;
    fn focus_mut<'a>(&self, root: &'a mut R) -> Option<&'a mut V>;
}

Reference-shaped KpTrait (Root = &R, Value = &V) with HRTB navigation.

Use Self::focus / Self::focus_mut for local borrows; Readable::get / Writable::set use the 'static link types and are intended for composition (KpTrait::then, etc.).

Required Methods

fn focus<'a>(&self, root: &'a R) -> Option<&'a V>

fn focus_mut<'a>(&self, root: &'a mut R) -> Option<&'a mut V>

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
