Enum TreePosition 

pub enum TreePosition {
    Root,
    Child {
        index: usize,
        len: usize,
        depth: usize,
    },
}

A visible value’s position in a Tree.

The optional root has no sibling group. Child positions are assigned after offsets and hidden nodes are removed, and top-level children have depth zero.

Variants

Root

The Tree’s optional root value.

Child

One node among its visible siblings.

Fields

index: usize

The zero-based visible sibling index.

len: usize

The number of visible siblings in this group.

depth: usize

The zero-based nesting depth used by the canonical connectors.

Trait Implementations

impl Clone for TreePosition

fn clone(&self) -> TreePosition

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for TreePosition

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for TreePosition

fn eq(&self, other: &TreePosition) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
