Thunderdome
Generational arena inspired by generational-arena, slotmap, and slab.
Basic Examples
let mut arena = new;
let foo = arena.insert;
let bar = arena.insert;
assert_eq!;
assert_eq!;
arena = "Replaced";
assert_eq!;
let foo_value = arena.remove;
assert_eq!;
// The slot previously used by foo will be reused for baz
let baz = arena.insert;
assert_eq!;
// foo is no longer a valid key
assert_eq!;

Minimum Supported Rust Version (MSRV)
Thunderdome supports Rust 1.31.0 and newer. Until Thunderdome reaches 1.0, changes to the MSRV will require major version bumps. After 1.0, MSRV changes will only require minor version bumps, but will need significant justification.
