Enum Query

pub enum Query {
    NodeID(usize),
    EdgeID(usize),
    Directed(DirectedEdge),
    Undirected(UndirectedEdge),
    Indeterminate(IndeterminateEdge),
}

Arguments

• index:

returns: Option<CowSelf::Node>

Examples

use graph_theory::GraphEngine;

Variants

NodeID(usize)

EdgeID(usize)

No need to remove anything

Directed(DirectedEdge)

Removed one node, return the node id

Undirected(UndirectedEdge)

Removed two nodes, return these node ids

Indeterminate(IndeterminateEdge)

Account for the fact that the graph is dynamic

Implementations

impl Query

pub fn as_entry(&self) -> GraphEntry

Arguments

• index:

returns: Option<CowSelf::Node>

Examples

use graph_theory::GraphEngine;

pub fn check_node_range(index: usize, count: usize) -> Result<usize, GraphError>

Returns the node as a node ID.

pub fn check_edge_range(index: usize, count: usize) -> Result<usize, GraphError>

Returns the node as a node ID.
