Bump bumpalo from 3.10.0 to 3.12.0 in /libursa

[dependabot]

Bumps bumpalo from 3.10.0 to 3.12.0.

Changelog

Sourced from bumpalo's changelog.

3.12.0

Released 2023-01-17.

Added

• Added the bumpalo::boxed::Box::bump and bumpalo::collections::String::bump getters to get the underlying Bump that a string or box was allocated into.

Changed

• Some uses of Box that MIRI did not previously consider as UB are now reported as UB, and bumpalo's internals have been adjusted to avoid the new UB.

---

3.11.1

Released 2022-10-18.

Security

• Fixed a bug where when std::vec::IntoIter was ported to bumpalo::collections::vec::IntoIter, it didn't get its underlying Bump's lifetime threaded through. This meant that rustc was not checking the borrows for bumpalo::collections::IntoIter and this could result in use-after-free bugs.

---

3.11.0

Released 2022-08-17.

Added

• Added support for per-Bump allocation limits. These are enforced only in the slow path when allocating new chunks in the Bump, not in the bump allocation hot path, and therefore impose near zero overhead.
• Added the bumpalo::boxed::Box::into_inner method.

Changed

• Updated to Rust 2021 edition.
• The minimum supported Rust version (MSRV) is now 1.56.0.
