Struct NodeMarks 

pub struct NodeMarks { /* private fields */ }

Marks on the nodes of one MemoryApplier, for one walk over its tree.

A mark is a byte; an unmarked node reads 0. Marks stay until NodeMarks::reset, and only a walk that leaves the applier’s tree as it is may keep them: a node stored again in another place loses its mark.

use cranpose_core::{MemoryApplier, NodeMarks};

let applier = MemoryApplier::new();
let mut marks = NodeMarks::default();
marks.reset(&applier);
assert_eq!(marks.get(&applier, 7), 0);
marks.set(&applier, 7, 2);
assert_eq!(marks.get(&applier, 7), 2);

Implementations

impl NodeMarks

pub fn reset(&mut self, applier: &MemoryApplier)

Unmarks every node, with room for every node applier holds now.

pub fn get(&self, applier: &MemoryApplier, id: NodeId) -> u8

The mark of id: 0 while it has none.

pub fn set(&mut self, applier: &MemoryApplier, id: NodeId, mark: u8)

Marks id with mark.

Trait Implementations

impl Default for NodeMarks

fn default() -> Self
