Struct DirNode 

pub struct DirNode {
    pub children: HashMap<String, DirNode>,
    pub file_size: u64,
    pub file_count: usize,
}

Intermediate tree node for building the hierarchy from filesystem paths.

Each node represents either a file (leaf with file_size > 0 and no children) or a directory (with children). Sizes aggregate upward via total_size().

Fields

children: HashMap<String, DirNode>

file_size: u64

Total size of files directly in this node (leaf files)

file_count: usize

Number of files directly in this node

Implementations

impl DirNode

pub fn new() -> Self

pub fn insert(&mut self, path_components: &[&str], size: u64)

Insert a file path into the tree, splitting on path separators.

pub fn total_size(&self) -> u64

Compute total size of this subtree.

pub fn total_file_count(&self) -> usize

Total number of files in this subtree.

pub fn to_echarts(&self, name: &str) -> EChartsNode

Convert to ECharts JSON tree, collapsing single-child directories.

Single-child directory chains are collapsed (e.g., a/b/c becomes a single node named "a/b/c") to reduce visual clutter.

Trait Implementations

impl Debug for DirNode

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

Formats the value using the given formatter.

impl Default for DirNode

fn default() -> Self

Returns the “default value” for a type.
