Source src/silo:std.collections.hashmap

1##! HashMap — hash-based key-value collection.
2##!
3##! The `HashMap` type is implicitly available everywhere; this module
4##! attaches `.insert`, `.get`, `.contains`, and `.len` to it via host
5##! intrinsics.
6##!
7##! Not re-exported by the prelude — use
8##! `:use :open silo:std.collections.hashmap ...`.
