Struct AnnotationStore 

pub struct AnnotationStore {
    pub by_instance: BTreeMap<String, Vec<Annotation>>,
}

All annotations on disk, keyed by SOP Instance UID.

Saved as pretty JSON to <data_dir>/annotations.json on every push, clear, or undo (the viewer favours safety over write-batching here — these files are tiny).

Fields

by_instance: BTreeMap<String, Vec<Annotation>>

SOP Instance UID → annotation list (in insertion order).

Implementations

impl AnnotationStore

pub fn load(path: &Path) -> Self

Load from a JSON sidecar. Missing or malformed files yield Self::default — annotations are an optional layer, not a hard requirement.

pub fn save(&self, path: &Path) -> Result<()>

Atomically(-ish) write the store to path as pretty JSON, creating the parent directory if needed.

pub fn for_instance(&self, uid: &str) -> &[Annotation]

Borrow the annotation list for uid, or an empty slice if absent.

pub fn push(&mut self, uid: &str, ann: Annotation)

Append ann to the list for uid.

pub fn clear_instance(&mut self, uid: &str)

Drop every annotation on uid.

pub fn pop_last(&mut self, uid: &str)

Pop the most recently pushed annotation on uid. Removes the per-instance entry entirely if the list becomes empty.
