[dependabot]

Bumps indexmap from 2.2.2 to 2.6.0.

Changelog

Sourced from indexmap's changelog.

2.6.0 (2024-10-01)

• Implemented Clone for map::IntoIter and set::IntoIter.
• Updated the hashbrown dependency to version 0.15.

2.5.0 (2024-08-30)

• Added an insert_before method to IndexMap and IndexSet, as an alternative to shift_insert with different behavior on existing entries.
• Added first_entry and last_entry methods to IndexMap.
• Added From implementations between IndexedEntry and OccupiedEntry.

2.4.0 (2024-08-13)

• Added methods IndexMap::append and IndexSet::append, moving all items from one map or set into another, and leaving the original capacity for reuse.

2.3.0 (2024-07-31)

• Added trait MutableEntryKey for opt-in mutable access to map entry keys.
• Added method MutableKeys::iter_mut2 for opt-in mutable iteration of map keys and values.

2.2.6 (2024-03-22)

• Added trait MutableValues for opt-in mutable access to set values.

2.2.5 (2024-02-29)

• Added optional borsh serialization support.

2.2.4 (2024-02-28)

• Added an insert_sorted method on IndexMap, IndexSet, and VacantEntry.
• Avoid hashing for lookups in single-entry maps.
• Limit preallocated memory in serde deserializers.

2.2.3 (2024-02-11)

• Added move_index and swap_indices methods to IndexedEntry, OccupiedEntry, and RawOccupiedEntryMut, functioning like the existing methods on IndexMap.
• Added shift_insert methods on VacantEntry and RawVacantEntryMut, as well as shift_insert_hashed_nocheck on the latter, to insert the new entry at a particular index.
• Added shift_insert methods on IndexMap and IndexSet to insert a new entry at a particular index, or else move an existing entry there.
