Version 0.6.0 (May 25, 2023)

Breaking Changes

  • The MSRV is now 1.61.

  • Storage was renamed to InitCell.

    The type was renamed to more accurately reflect its intended use and be more consistent with naming across the ecosystem. Several method names were also changed accordingly:

    • Storage::get_or_set() was renamed to InitCell::get_or_init().
    • Storage::set_or_get() was renamed to InitCell::set_or_init().

    Along with naming changes, the following improvements were made:

    • InitCell<T> can be constructed and used even with T: !Sync + !Send.
    • InitCell<T> impls Send even when T: !Sync.
    • Added InitCell::{wait, reset, take, update}() methods.

  • LocalStorage was renamed to LocalInitCell.

    No other changes were made to the API.

  • Container was renamed to TypeMap.

    The type was renamed to more accurately reflect its intended use and be more consistent with naming across the ecosystem. The following changes were also made:

    • Container![] is neither Sync nor Send.
    • An internal implementation detail was modified to more thoroughly ensure forwards-compatibility with Rust releases. This resulted in several uses of unsafe being removed at the cost of raising the MSRV to 1.61.

General Improvements

  • The crate now uses edition 2021.
  • LocalInitCell::try_get() no longer panics when thread-local storage is not available.
