Struct Store

pub struct Store<'a, T, R> { /* private fields */ }

Storage for collaborative objects of a specific type T in a single repository.

Implementations

impl<'a, T, R> Store<'a, T, R>

where R: ReadRepository + Store,

pub fn open_for( type_name: &'a TypeName, repo: &'a R, ) -> Result<Store<'a, T, R>, Error>

Open a new generic store.

pub fn identity(self, identity: Oid) -> Store<'a, T, R>

Return a new store with the attached identity.

impl<'a, T, R> Store<'a, T, R>

where R: ReadRepository + Store<Namespace = PublicKey>, T: CobWithType,

pub fn open(repo: &'a R) -> Result<Store<'a, T, R>, Error>

Open a new generic store.

impl<T, R> Store<'_, T, R>

where G: Signer<Signature>,

Create an object.

pub fn remove<G>(&self, id: &ObjectId, signer: &Device<G>) -> Result<(), Error>

where G: Signer<Signature>,

Remove an object.

impl<'a, T, R> Store<'a, T, R>

where R: ReadRepository + Store, T: Cob + Evaluate<R> + 'a, <T as Cob>::Action: Serialize,

pub fn get(&self, id: &ObjectId) -> Result<Option<T>, Error>

Get an object.

pub fn all(&self) -> Result<impl ExactSizeIterator + 'a, Error>

Return all objects.

pub fn is_empty(&self) -> Result<bool, Error>

Return true if the list of issues is empty.

pub fn count(&self) -> Result<usize, Error>

Return objects count.

Trait Implementations

impl<T, R> AsRef<R> for Store<'_, T, R>

fn as_ref(&self) -> &R

Converts this type into a shared reference of the (usually inferred) input type.
