type EntryMut<'i>: DerefMut<Target = V> where Self: 'i

Required Methods

fn get_entry<'i, Q>(&'i self, query: Q) -> V

where Q: Into<Query>,

Get the reference of data by given query from the storage.

Examples

use graph_theory::GraphEngine;

fn try_entry<'i, Q>( &'i self, query: Q, ) -> Result<Self::EntryRef<'i>, GraphError>

where Q: Into<Query>,

Get the reference of data by given query from the storage.

Examples

use graph_theory::GraphEngine;

fn mut_entry<'i, Q>( &'i mut self, query: Q, ) -> Result<Self::EntryMut<'i>, GraphError>

where Q: Into<Query>,

Get the reference of data by given query from the storage.

Examples

use graph_theory::GraphEngine;

Provided Methods

fn set_entry<'i, Q>(&'i mut self, query: Q, entry: V) -> Result<(), GraphError>

where Q: Into<Query>,

Get the reference of data by given query from the storage.

Examples

use graph_theory::GraphEngine;

fn get_node_data<'i>(&'i self, node: usize) -> V

fn try_node_data<'i>(&'i self, node: usize) -> Option<Self::EntryRef<'i>>

fn mut_node_data<'i>(&'i mut self, node: usize) -> Option<Self::EntryMut<'i>>

fn set_node_data<'i>(&'i mut self, node: usize, data: V)

fn get_edge_data<'i>(&'i self, edge: usize) -> V

fn try_edge_data<'i>(&'i self, edge: usize) -> Option<Self::EntryRef<'i>>

fn mut_edge_data<'i>(&'i mut self, edge: usize) -> Option<Self::EntryMut<'i>>

fn set_edge_data<'i>(&'i mut self, edge: usize, data: V)

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.

Implementors

impl<V> EntryEngine<V> for ListStorage<V>

where V: Clone,

type EntryRef<'i> = &'i V where V: 'i

type EntryMut<'i> = &'i mut V where V: 'i
