[−][src]Trait entity::prelude::Database
Represents a synchronous database, which performs blocking CRUD operations using ents. Given that many database implementations handle interior mutability themselves, the API of this trait does not provide any mut guarantees itself.
Required methods
pub fn get(&self, id: Id) -> DatabaseResult<Option<Box<dyn Ent>>>
[src]
Retrieves a copy of a single, generic ent with the corresponding id
This should not connect the ent back to the database upon return as that decision should be made outside of the database itself.
pub fn remove(&self, id: Id) -> DatabaseResult<bool>
[src]
Removes the ent with the corresponding id, triggering edge processing for all disconnected ents. Returns a boolean indicating if an ent was removed.
pub fn insert(&self, ent: Box<dyn Ent>) -> DatabaseResult<Id>
[src]
Inserts a new ent using its id as the primary index, overwriting any ent with a matching id. If the ent's id is set to the ephemeral id (of 0), a unique id will be assigned to the ent prior to being inserted.
The ent's id is returned after being inserted.
pub fn get_all(&self, ids: Vec<Id>) -> DatabaseResult<Vec<Box<dyn Ent>>>
[src]
Performs a retrieval of multiple ents of any type
pub fn find_all(&self, query: Query) -> DatabaseResult<Vec<Box<dyn Ent>>>
[src]
Finds all generic ents that match the query
