Trait TreeDisplayContext 

pub trait TreeDisplayContext<N: ?Sized> {
    // Provided methods
    fn push_parent(&mut self, parent: &N) { ... }
    fn pop_parent(&mut self, parent: &N) { ... }
}

Traversal state updated as a tree renderer enters and leaves a node’s children.

The context visible while a node is rendered describes its ancestors. The renderer calls Self::push_parent before visiting the node’s children and Self::pop_parent afterwards.

Provided Methods

fn push_parent(&mut self, parent: &N)

Record parent while its children are visited.

fn pop_parent(&mut self, parent: &N)

Remove parent after all of its children have been visited.

Dyn Compatibility

This trait is dyn compatible.

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