pub enum NarNode {
    File {
        executable: bool,
        contents: Vec<u8>,
    },

Implementations

impl NarNode

pub fn walk<F: FnMut(&str, &NarNode)>(&self, visitor: &mut F)

Walk the tree top-down, calling visitor on every node with its relative path ("" for the root).

pub fn file_count(&self) -> usize

Count files in the tree (excluding directories + symlinks).

pub fn total_bytes(&self) -> u64

Total bytes of file contents in the tree.

pub fn at_path(&self, path: &str) -> Option<&NarNode>

Find a node by path (relative, /-separated). Returns None if the path doesn’t exist in the tree.
