Dungeon Cell

A cell type that can store any static type, no allocations required.

This crate is #![no_std].

lib.rs:

Dungeon Cell

Cell and Cell-like types that can store any static type without dynamic memory.

Currently only the core primitive is implemented (unsized, cell, stack vec, ... are in progress).

Example

use dungeon_cell::{DungeonCore, layout_for};

let mut c: DungeonCore<layout_for!(i32, f64)> = DungeonCore::new();

// we can store a i32 and get it back
c.store(1234);
assert_eq!(c.take::<i32>(), Some(1234));

// we can store a f64 and get it back
c.store(1.234);
assert_eq!(c.take::<f64>(), Some(1.234));

// we can't take a type the core isn't storing
c.store(1234);
assert_eq!(c.take::<f64>(), None);

// we can borrow both unique and shared
c.store(1234);
*c.borrow_mut::<i32>().unwrap() += 10;
assert_eq!(c.borrow::<i32>(), Some(&1244));
