NameCache

recall_echo::graph::edge_view

Struct NameCache 

Source 
pub struct NameCache { /* private fields */ }
Expand description

Resolves record ids to entity names, once per id.

Rendering the edges of one entity asks for the same neighbour repeatedly; rendering a whole overview asks for the same hub over and over. One lookup each is enough.

Implementations§

Source§

impl NameCache

Source

pub fn new() -> Self

Source

pub async fn name_of( &mut self, db: &Surreal<Db>, id: &str, ) -> Result<String, GraphError>

The entity’s name, or its record id when no entity is stored under it.

A dangling edge is still worth showing — it is precisely the sort of thing a person inspecting their memory should be able to see and delete.
