Rust: Tracking Issue for `destructuring_assignment`

[varkor]

This is a tracking issue for the RFC "Destructuring assignment" (https://github.com/rust-lang/rfcs/pull/2909).
The feature gate for the issue is #![feature(destructuring_assignment)].

About tracking issues

Tracking issues are used to record the overall progress of implementation.
They are also uses as hubs connecting to other relevant issues, e.g., bugs or open design questions.
A tracking issue is however not meant for large scale discussion, questions, or bug reports about a feature.
Instead, open a dedicated issue for the specific matter and add the relevant feature gate label.

Implementation history

The initial implementation was carried out in three steps by @fanzier (split out from an initial implementation, https://github.com/rust-lang/rust/pull/71156):

• Implementing destructuring support for tuples: https://github.com/rust-lang/rust/pull/78748
• Implementing destructuring support for structs and slices: https://github.com/rust-lang/rust/pull/78836
• Implementing destructuring support for _ expressions: https://github.com/rust-lang/rust/pull/79016

[varkor]

We've opened an RFC for destructuring assignment: https://github.com/rust-lang/rfcs/pull/2909.

Now that #78748, #78836, and #79016 have been merged, destructuring assignment is now implemented. Thanks to @fanzier for their hard work implementing this feature!
