Expand description

Incremental mutation support for stores that can delete elements.

Deletes are idempotent: removing an element that does not exist is not an error.

Required Methods§

Source

fn delete_node<'life0, 'life1, 'async_trait>( &'life0 self, id: &'life1 NodeId, ) -> Pin<Box<dyn Future<Output = Result<()>> + Send + 'async_trait>>
where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

Deletes a node and all edges incident to it.

Source

fn delete_edge<'life0, 'life1, 'life2, 'life3, 'async_trait>( &'life0 self, from: &'life1 NodeId, label: &'life2 Label, to: &'life3 NodeId, ) -> Pin<Box<dyn Future<Output = Result<()>> + Send + 'async_trait>>
where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait, 'life2: 'async_trait, 'life3: 'async_trait,

Deletes the edge(s) matching (from, label, to).

Provided Methods§

Source

fn apply_mutations<'life0, 'life1, 'async_trait>( &'life0 self, mutations: &'life1 [GraphMutation], ) -> Pin<Box<dyn Future<Output = Result<()>> + Send + 'async_trait>>
where Self: Sync + 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

Applies mutations in order, stopping at the first error.

Dyn Compatibility§

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
