pub struct HandleGenExample { /* private fields */ }
Expand description

🫆 An example generational handle.


📍 data/id/handle::HandleGenExample

📦 size_of::<HandleGenExample>() == 4 bytes / 32 bits ⚗️Option<T> 🟰 T


Generated by handle_gen!.

Demonstrates a generational handle with an index and niche-aware generation.

§Methods

  • Core handle methods: new, from_prim, try_from_usize, into_parts, into_prim, eq.
  • Component access: each field exposes get_<field>, get_<field>_prim, and get_<field>_usize.
  • Canonical Word representation: raw, from_raw, try_from_raw.
  • Scalar packing: PACK_BITS, try_pack_u8try_pack_u128, try_unpack_u8try_unpack_u128.
