Struct TreeInputs 

pub struct TreeInputs<'a> {
    pub graph: &'a PackageGraph,
    pub roots: &'a [usize],
    pub lockfile: Option<&'a Lockfile>,
    pub active_patches: Option<&'a ActivePatchSet>,
    pub kind_filter: Option<DependencyKind>,
}

Per-call options for build_tree. Mirrors the same dependency-kind filter cabin tree --kind ... exposes, plus the optional Lockfile / patch / vendor / source-replacement inputs used to color provenance.

Fields

graph: &'a PackageGraph

Resolved package graph.

roots: &'a [usize]

Indices of packages the user selected as roots. Children are walked from these. Empty falls back to the graph’s primary set so callers do not have to special-case “no selection” themselves.

lockfile: Option<&'a Lockfile>

Optional lockfile contributing version-pinned checksums to the provenance label.

active_patches: Option<&'a ActivePatchSet>

Active patch entries. Patched packages are flagged with SourceProvenance::Patched regardless of the lockfile.

kind_filter: Option<DependencyKind>

Restrict the walk to a single dependency-kind edge. None walks every kind the graph carries.
