[−][src]Struct qualia::Checkpoint

pub struct Checkpoint<'a> { /* fields omitted */ }

A set of not-yet-committed changes to a Store, as created by Store::checkpoint().

Implementations

impl<'a> Checkpoint<'a>[src]

pub fn commit(self, description: impl AsRef<str>) -> Result<()>[src]

Commit this transaction with the given description.

pub fn add(&self, object: Object) -> Result<i64>[src]

Add an object to the store.

Returns the ID of the newly created object.

pub fn query(&self, query: impl Into<QueryNode>) -> MutableCollection<'_>[src]

Get a MutableCollection of the objects matching the given query.

This can take either a QueryNode or QueryBuilder; you almost certainly want to use the latter.

Methods from Deref<Target = Store>

pub fn all(&self) -> Collection<'_>[src]

Get a Collection of all objects.

pub fn query(&self, query: impl Into<QueryNode>) -> Collection<'_>[src]

Get a Collection of the objects matching the given query.

This can take either a QueryNode or QueryBuilder; you almost certainly want to use the latter.
