Struct BTreeDatumStore 

pub struct BTreeDatumStore { /* private fields */ }

In-memory DatumStore backed by a BTreeMap; the kernel default.

Implementations

impl BTreeDatumStore

pub fn new() -> Self

Creates an empty store.

pub fn len(&self) -> usize

Returns the number of interned datums.

pub fn is_empty(&self) -> bool

Returns whether the store holds no datums.

Trait Implementations

impl Clone for BTreeDatumStore

fn clone(&self) -> BTreeDatumStore

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl DatumStore for BTreeDatumStore

fn intern(&mut self, datum: Datum) -> Result<ContentId>

Interns datum, returning its ContentId; re-interning equal data is idempotent.

fn get(&self, id: &ContentId) -> Result<Option<&Datum>>

Resolves the datum for id, or None when it is not stored here.

fn contains(&self, id: &ContentId) -> bool

Returns whether id is interned in this store.

impl Debug for BTreeDatumStore

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for BTreeDatumStore

fn default() -> BTreeDatumStore

Returns the “default value” for a type.
