Struct indradb::MemoryDatastore

pub struct MemoryDatastore { /* fields omitted */ }

An in-memory datastore.

Implementations

impl MemoryDatastore

pub fn read<P: Into<PathBuf>>(
    path: P
) -> StdResult<MemoryDatastore, BincodeError>

Reads a persisted image from disk. Calls to sync will overwrite the file at the specified path.

Arguments

• path: The path to the persisted image.

pub fn create<P: Into<PathBuf>>(
    path: P
) -> StdResult<MemoryDatastore, BincodeError>

Creates a new datastore. Calls to sync will overwrite the file at the specified path, but as opposed to read, this will not read the file first.

Arguments

• path: The path to the persisted image.

Trait Implementations

impl Clone for MemoryDatastore

fn clone(&self) -> MemoryDatastore

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Datastore for MemoryDatastore

type Trans = MemoryTransaction

fn sync(&self) -> Result<()>

Syncs persisted content. Depending on the datastore implementation, this has different meanings - including potentially being a no-op.

fn transaction(&self) -> Result<Self::Trans>

Creates a new transaction.

fn bulk_insert<I>(&self, items: I) -> Result<()> where
    I: Iterator<Item = BulkInsertItem>, 

Bulk inserts many vertices, edges, and/or properties.

impl Debug for MemoryDatastore

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

Formats the value using the given formatter.

impl Default for MemoryDatastore

fn default() -> MemoryDatastore

Returns the "default value" for a type.
