Trait Node 

pub(crate) trait Node: Clone {
    // Required methods
    fn adopt(&mut self, key: &str, source: &Self);
    fn adopt_shell(&mut self, key: &str, source: &Self);
    fn child(&self, key: &str) -> Option<&Self>;
    fn child_mut(&mut self, key: &str) -> Option<&mut Self>;
    fn is_container(&self) -> bool;
    fn keys(&self) -> impl Iterator<Item = &str> + '_;
    fn remove(&mut self, key: &str);

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

A node of a format’s document tree that the merge can edit in place.

Required Methods

fn adopt(&mut self, key: &str, source: &Self)

Take the child key from source, replacing the existing child or appending. An existing child keeps its decor unless the desired child brings a comment of its own, which replaces the leading comment.

fn adopt_shell(&mut self, key: &str, source: &Self)

Insert an empty container for the child key of source, with the decor and comment of that child.

fn child(&self, key: &str) -> Option<&Self>

fn child_mut(&mut self, key: &str) -> Option<&mut Self>

fn is_container(&self) -> bool

Whether this node holds keyed children.

fn keys(&self) -> impl Iterator<Item = &str> + '_

The child keys in order. Empty for leaves.

fn remove(&mut self, key: &str)

Provided Methods

fn is_empty(&self) -> bool

Whether this node has no children.

Dyn Compatibility

This trait is not dyn compatible.

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