Struct Handle 

pub struct Handle {
    pub path: String,
    pub index: Option<u32>,
}

Handle. Used for referencing nodes within a MachGraph.

Fields

path: String

Name of the node (is a dot-separated path in a search).

index: Option<u32>

Index of the node in the graph.

Implementations

impl Handle

Handle implementation.

pub fn has_index(&self) -> bool

Has index?

pub fn get_index(&self, graph: &MachGraph) -> Option<u32>

Get index.

pub fn set_index(&mut self, graph: &MachGraph)

Set index.

pub fn set_path(&mut self, graph: &MachGraph)

Set path.

pub fn path(graph: &MachGraph, index: u32) -> Option<String>

Get a path for an index.

pub fn index(graph: &MachGraph, path: &String) -> Option<u32>

Get an index for a path. Does the best it can with the path provided.
