[][src]Enum plexus::graph::Selector

pub enum Selector<K> {

Topology selector.

Identifies topology by key or index. Keys behave as an absolute selector and uniquely identify a single topological structure. Indices behave as a relative selector and identify topological structures relative to some other structure. Selector is used by operations that support both of these selection mechanisms.

An index is typically used to select a neighbor or contained (and ordered) topological structure, such as a neighboring face.


Splitting a face by index (of its contained vertices):

use decorum::N64;
use nalgebra::Point3;
use plexus::graph::MeshGraph;
use plexus::prelude::*;
use plexus::primitive::cube::Cube;
use plexus::primitive::generate::Position;

let mut graph = Cube::new()
let key = graph.faces().nth(0).unwrap().key();
    .split(ByIndex(0), ByIndex(2))




impl<K> Selector<K>[src]

pub fn key_or_else<E, F>(self, f: F) -> Result<K, GraphError> where
    E: Into<GraphError>,
    F: Fn(usize) -> Result<K, E>, 

Gets the selector's key or passes its index to a function to resolve the key.

pub fn index_or_else<E, F>(self, f: F) -> Result<usize, GraphError> where
    E: Into<GraphError>,
    F: Fn(K) -> Result<usize, E>, 

Gets the selector's index or passes its key to a function to resolve the index.
