Sourced from indexmap's changelog.

• 2.0.2

  • The hashbrown dependency has been updated to version 0.14.1 to complete the support for Rust 1.63.

• 2.0.1

  • MSRV: Rust 1.63.0 is now supported as well, pending publication of hashbrown's relaxed MSRV (or use cargo --ignore-rust-version).

• 2.0.0

  • MSRV: Rust 1.64.0 or later is now required.

  • The "std" feature is no longer auto-detected. It is included in the default feature set, or else can be enabled like any other Cargo feature.

  • The "serde-1" feature has been removed, leaving just the optional "serde" dependency to be enabled like a feature itself.

  • IndexMap::get_index_mut now returns Option<(&K, &mut V)>, changing the key part from &mut K to &K. There is also a new alternative MutableKeys::get_index_mut2 to access the former behavior.

  • The new map::Slice<K, V> and set::Slice<T> offer a linear view of maps and sets, behaving a lot like normal [(K, V)] and [T] slices. Notably, comparison traits like Eq only consider items in order, rather than hash lookups, and slices even implement Hash.

  • IndexMap and IndexSet now have sort_by_cached_key and par_sort_by_cached_key methods which perform stable sorts in place using a key extraction function.

  • IndexMap and IndexSet now have reserve_exact, try_reserve, and try_reserve_exact methods that correspond to the same methods on Vec. However, exactness only applies to the direct capacity for items, while the raw hash table still follows its own rules for capacity and load factor.

  • The Equivalent trait is now re-exported from the equivalent crate, intended as a common base to allow types to work with multiple map types.

  • The hashbrown dependency has been updated to version 0.14.

  • The serde_seq module has been moved from the crate root to below the map module.
