Changelog

  • Avoid transmute on references: To avoid issues with (possible) future changes in Rust, the storable module doesn't use transmute on references anymore. Instead, std::slice::from_raw_parts, std::str::from_utf8_unchecked, and str::as_bytes() are used.
• 2022-04-11: Version 0.0.2
  • Moved Storable, StorableConstBytesLen, and StorableWithOwned traits to new (public) storable module (but Storable gets re-exported by crate-level module)
