Observations/Thoughts
A Rust team deadlocked a `tokio::sync::Mutex` without holding the lock by wrapping it in a `PausableFuture` that violated the waker contract, preventing permit release.
A deep dive into debugging Meilisearch memory leaks, revealing issues with `bumpalo::Vec` and C dependency (LMDB) allocator mismatches, ultimately resolved by unifying allocators and upgrading to mimalloc v3.
Maximally minimal view types smallcultfollowing.com
A proposal for 'view types' (`&mut self { fields }`) to allow field-specific mutable borrows, enabling the borrow checker to resolve common `self` aliasing conflicts and simplify code.
This benchmark compares performance of `sort_by_unicase`, `sort_by_cached_lowercase`, and `sort_by_iter_lowercase` for case-insensitive string sorting.
What If Traits Carried Values nadrieril.github.io
A conceptual language feature for global capabilities that serve as implicit, scope-bound arguments within `where` clauses.
Presents a `with`-clause and `eff` keyword-based notation for a unified effect system in Rust, enabling explicit declaration, generics, and algebraic reasoning for capabilities like async and fallibility.
Rust threads on the GPU www.vectorware.com
Rust's `std::thread` now runs on GPUs by mapping threads to warps, unlocking a significant portion of the Rust ecosystem for GPU-native applications.
Models Rust traits in "dictionary-passing style" to make trait elaboration explicit, aiming for a more robust and sound compiler.
Rust Walkthroughs
Explores roots of unity and their role in enabling efficient $O(N \log N)$ polynomial interpolation and evaluation via NTT, crucial for Rust-based ZK-SNARKs.
Explore a research-focused Rust SIMD CSV parser that uses nibble lookup tables for branchless classification, prefix XOR for quote filtering, and `clz` for boundary detection, inspired by `simdjson`.
This article explores building a Language Server Protocol (LSP) server in Rust using `tower-lsp-server` to unify code logic across various editors and platforms, demonstrating basic functionality, custom autocompletion, text modification, and even AI chatbot integration.
An Incoherent Rust www.boxyuwu.blog
This article proposes "incoherent traits" enabled by named impls and explicit trait bound parameters to address how Rust's coherence rules hinder ecosystem evolution, while preserving soundness and avoiding the "HashMap problem."
A detailed guide on integrating Rust into a large Waf-based C codebase, covering build system orchestration, environment sharing via JSON, FFI with a custom Bindgen, and Cargo workspace feature unification.
