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

pub enum Selector<K> {

Entity selector.

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

An index is typically used to select an adjacent entity or contained (and ordered) entity, such as an adjacent 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.
