Struct SledDatabase 

pub struct SledDatabase(/* private fields */);

Represents a sled database that performs synchronous insertion, retrieval, and removal. Sled maintains disk-backed data, so the serde feature has no purpose with this database.

Sled itself is thread-safe, maintaining an internal Arc for each tree; therefore, this database can be cloned to increment those counters.

Implementations

impl SledDatabase

pub fn new(db: Db) -> Self

Creates a new instance of the database wrapping a sled::Db

pub fn ids(&self) -> HashSet<Id>

Returns ids of all ents stored in the database

pub fn has_id(&self, id: Id) -> bool

Returns true if database contains the provided id

pub fn ids_for_type(&self, type: &str) -> HashSet<Id>

Returns ids of all ents for the given type

Trait Implementations

impl Clone for SledDatabase

fn clone(&self) -> SledDatabase

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Database for SledDatabase

fn get_all(&self, ids: Vec<Id>) -> DatabaseResult<Vec<Box<dyn Ent>>>

Performs a retrieval of multiple ents of any type

fn find_all(&self, query: Query) -> DatabaseResult<Vec<Box<dyn Ent>>>

Finds all generic ents that match the query

fn get(&self, id: Id) -> DatabaseResult<Option<Box<dyn Ent>>>

Retrieves a copy of a single, generic ent with the corresponding id

fn remove(&self, id: Id) -> DatabaseResult<bool>

Removes the ent with the corresponding id, triggering edge processing for all disconnected ents. Returns a boolean indicating if an ent was removed.

fn insert(&self, ent: Box<dyn Ent>) -> DatabaseResult<Id>

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.
