Struct grin_store::Store

pub struct Store { /* fields omitted */ }

LMDB-backed store facilitating data access and serialization. All writes are done through a Batch abstraction providing atomicity.

Methods

impl Store

pub fn open(env: Arc<Environment>, name: &str) -> Store

Creates a new store with the provided name under the specified environment

pub fn get(&self, key: &[u8]) -> Result<Option<Vec<u8>>, Error>

Gets a value from the db, provided its key

pub fn get_ser<T: Readable>(&self, key: &[u8]) -> Result<Option<T>, Error>

Gets a Readable value from the db, provided its key. Encapsulates serialization.

pub fn exists(&self, key: &[u8]) -> Result<bool, Error>

Whether the provided key exists

pub fn iter<T: Readable>(&self, from: &[u8]) -> Result<SerIterator<T>, Error>

Produces an iterator of Readable types moving forward from the provided key.

pub fn batch(&self) -> Result<Batch, Error>

Builds a new batch to be used with this store.
