Struct LabelRegistry 

pub struct LabelRegistry {
    pub labels: Vec<Label>,
    pub assignments: BTreeMap<String, Vec<String>>,
}

The whole taxonomy: an ordered list of labels plus fleet → label-ids.

assignments order is meaningful (index 0 is the primary label); the map itself is a BTreeMap so the serialized file is stable across saves.

Fields

labels: Vec<Label>

assignments: BTreeMap<String, Vec<String>>

Implementations

impl LabelRegistry

pub fn contains(&self, id: &str) -> bool

pub fn get(&self, id: &str) -> Option<&Label>

pub fn labels_of(&self, fleet: &str) -> &[String]

Labels assigned to a fleet, primary first. Empty when unassigned.

pub fn primary_of(&self, fleet: &str) -> Option<&str>

The group a fleet belongs to: its first label, or None for Ungrouped.

pub fn fleet_count(&self, id: &str) -> usize

How many fleets carry a label (in any position).

pub fn normalize(&mut self)

Self-heal a registry that may have been hand-edited: drop invalid or unknown label ids, de-duplicate while keeping first-wins order (so the primary survives), and drop fleets left with nothing.

pub fn set_labels(&mut self, fleet: &str, ids: Vec<String>)

Replace a fleet’s labels (order = priority; first is primary).

pub fn delete_label(&mut self, id: &str)

Remove a label everywhere: from the list and from every assignment. Fleets fall back to their next label, or become Ungrouped.

pub fn rename_label(&mut self, id: &str, display: &str) -> bool

Rename a label’s display text (the id, being the key, is stable).

pub fn prune(&mut self, existing_fleets: &[String])

Forget assignments for fleets that no longer exist on disk.
