Struct ArchiveNavigator 

pub struct ArchiveNavigator {
    pub entries: Vec<ArchiveEntry>,
    pub manifest: FxarManifest,
    pub selected: usize,
}

Builds and navigates a virtual directory tree from a flat FXAR manifest.

Fields

entries: Vec<ArchiveEntry>

Flat array of all nodes (root at index 0, then others).

manifest: FxarManifest

selected: usize

Selected node index (for TUI cursor).

Implementations

impl ArchiveNavigator

pub fn from_manifest(manifest: FxarManifest) -> Result<Self>

Open the manifest and build the virtual tree.

pub fn root(&self) -> &ArchiveEntry

pub fn entry_at(&self, idx: usize) -> Option<&ArchiveEntry>

pub fn children_of(&self, idx: usize) -> &[usize]

pub fn parent_of(&self, idx: usize) -> Option<usize>

pub fn manifest_entry_for(&self, idx: usize) -> Option<&FxarManifestEntry>

pub fn select_next(&mut self)

pub fn select_prev(&mut self)

pub fn selected_entry(&self) -> Option<&ArchiveEntry>

pub fn list_snapshots(&self) -> &[String]

Returns the list of snapshot names from the manifest.

pub fn snapshot_entry_count(&self, snapshot: &str) -> usize

Count entries (files and dirs) whose path starts with snapshot/ or equals snapshot.

pub fn visible_entry_indices(&self, snapshot_filter: Option<&str>) -> Vec<usize>

Returns the set of entry indices visible under a snapshot filter. If snapshot_filter is None, returns all entry indices. If Some(snap), returns: root (0) + snap node + all nodes under snap.
