Struct RuntimeMetadataTable 

pub struct RuntimeMetadataTable { /* private fields */ }

In-memory label table keyed by MetadataScope.

Operations replace label sets wholesale (no merge). Callers wanting merge semantics should read first, mutate the map, then write it back.

Implementations

impl RuntimeMetadataTable

pub fn new() -> Self

Create an empty table.

pub async fn set_labels( &self, scope: MetadataScope, labels: BTreeMap<String, String>, )

Replace the label set for scope. An empty labels map clears the entry.

pub async fn get_labels( &self, scope: &MetadataScope, ) -> BTreeMap<String, String>

Return the label set for scope, or an empty map if none is set.

pub async fn delete_labels( &self, scope: &MetadataScope, ) -> Option<BTreeMap<String, String>>

Remove the label set for scope. Returns the previous value if any.

pub async fn list_labels_for_mob( &self, mob_id: &str, ) -> Vec<(MetadataScope, BTreeMap<String, String>)>

Return all label sets associated with a mob — both the mob-scoped entry (if any) and every run-scoped entry whose mob id matches.
