Struct PathMap 

pub struct PathMap { /* private fields */ }

Stores path sequences as lists of dynamic pool indices. Index 0 is reserved as null.

Implementations

impl PathMap

pub fn new() -> Self

pub fn push(&mut self, indices: Vec<u16>) -> u16

Appends a path (as dynamic pool indices) and returns its index.

Examples

use state_engine::common::pool::PathMap;

let mut map = PathMap::new();
let idx = map.push(vec![1, 2, 3]);

assert_ne!(idx, 0);
assert_eq!(map.get(idx), Some([1u16, 2, 3].as_slice()));
assert_eq!(map.get(0), Some([].as_slice())); // null slot
assert_eq!(map.get(999), None);

pub fn get(&self, index: u16) -> Option<&[u16]>

Returns the path indices at the given index.

Trait Implementations

impl Default for PathMap

fn default() -> Self

Returns the “default value” for a type.
