Struct NodeView 

pub struct NodeView<'a> {
    pub node: &'a Node,
    pub arena: &'a NodeArena,
    pub index: NodeIndex,
}

A view into a node that provides convenient access to both the Node header and its type-specific data. This avoids the need to pass the arena around when working with node data.

Fields

node: &'a Node

arena: &'a NodeArena

index: NodeIndex

Implementations
