Trait Writable 

pub trait Writable<MutRoot, MutValue> {
    // Required method
    fn set(&self, root: MutRoot) -> Option<MutValue>;
}

Mutable keypath: setter path (same semantics as a get_mut closure on many keypath APIs).

Required Methods

fn set(&self, root: MutRoot) -> Option<MutValue>

Setter path. Returns None when navigation fails.

Dyn Compatibility

This trait is dyn compatible.

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