Trait TreeSort 

pub trait TreeSort<T: TreeModel> {
    // Required method
    fn compare(&self, model: &T, left: T::Id, right: T::Id) -> Ordering;

    // Provided method
    fn is_enabled(&self) -> bool { ... }
}

A policy for sorting sibling nodes.

Required Methods

fn compare(&self, model: &T, left: T::Id, right: T::Id) -> Ordering

Compares two sibling nodes.

Provided Methods

fn is_enabled(&self) -> bool

Returns true when sorting should be applied.

Dyn Compatibility

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