Implementations

impl DocumentStats

pub fn new() -> Self

Create a new empty statistics object

pub fn from_node(node: &Node) -> Self

Gather statistics from a Node tree

Example

let doc = Node::Array(vec![
    Node::from(1),
    Node::from("text"),
    Node::Array(vec![Node::from(2)])
]);

let stats = DocumentStats::from_node(&doc);
assert_eq!(stats.total_nodes, 5);
assert_eq!(stats.max_depth, 2);
assert_eq!(stats.array_count, 2);

pub fn estimated_memory_bytes(&self) -> usize

Calculate estimated memory usage in bytes

pub fn summary(&self) -> String

Get a human-readable summary

Trait Implementations

impl Clone for DocumentStats

fn clone(&self) -> DocumentStats

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for DocumentStats

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

Formats the value using the given formatter.

impl Default for DocumentStats

fn default() -> DocumentStats

Returns the “default value” for a type.
