Open-source Contributions

I have fixed bugs, improved heuristics, stabilized features, and significantly cleaned up code over a few open-source projects over time. This is in addition to my own projects, some of which have become quite large.

Projects are in no particular order. Contributions within a project are listed in reverse chronological order.

Rust

• rust#148375 optimizes panics, measurably improving compile time, memory usage, and binary size.
• rust#141754 implements the first phase of the restrictions RFC.
• RFC 3796 proposes permitting &&, ||, and ! in cfg.
• RFC 3681 proposes default values for individual fields and new syntax for using these selectively. While the RFC was not posted by me, I was significantly involved in the drafting.
• rust#116016 destabilizes RustcEncodable and RustcDecodable and removes them from the prelude. rust#123182 followed up to avoid compilation errors.
• rust#114238 fixes a bug in Duration::checked_div.
• RFC 3458 proposes unsafe fields.
• rust#111571 alters the API of proc_macro::Span in anticipation of stabilization.
• rust#108200 implements an optimized Damerau-Levenshtein algorithm to provide better suggestions in compiler diagnostics. cargo#11963 does the same for Cargo.
• RFC 3323 proposes "restrictions", a form of read-only fields and sealed traits.
• rust#101555 stabilizes #![feature(mixed_integer_ops)].
• rust#100315 stringifies visibilities correctly.
• rust#98115 removes the transitional diagnostics for #[rustc_deprecated].
• rust#97254 removes the crate visibility modifier from the language.
• rust#97239 removes all uses of the crate visibility modifier.
• rust#95960 and stdarch#1301 remove the #[rustc_deprecated] attribute in favor of #[deprecated]. rustc-dev-guide#1338 and rust-analyzer#11983 were also submitted to ensure a seamless transition.
• rust#94635 merges the #[deprecated] and #[rustc_deprecated] attributes. It also permits suggested replacements for deprecated items on nightly.
• rust#94461 creates the 2024 edition on nightly.
• rust#94457 stabilizes #[derive(Default)] on enums, where the default is indicated by placing a #[default] attribute on the desired unit variant.
• rust#94455 stabilizes div_floor, div_ceil, next_multiple_of, and checked_next_multiple_of for all integer types.
• rust#93960 implements proper stability checks for impl const Trait and falls back to being unstable const when undeclared. With minimal change, this was merged as rust#97177 .
• rust#91148 uses derive_default_enum in the compiler.
• rust#90998 requires a const-stability attribute on all publicly reachable const methods.
• rust#90935 alphabetizes language features, significantly reducing the frequency of merge conflicts.
• rust#90897 fixes the feature flags used for some features.
• rust#90896 stabilizes part of MaybeUninit as const fn in Rust 1.59.
• rust#90687 fixes a bug where some const panics couldn't be used in the standard library.
• rust#90521 stabilizes destructuring assignment in Rust 1.58.
• rust#89551 stabilizes dereferencing *const T in const contexts in Rust 1.58.
• rust#89542 stabilizes some Duration methods as const fn in Rust 1.58.
• rust#89509 stabilizes unreachable_unchecked as const fn in Rust 1.57.
• rust#89508 stabilizes panicking in const contexts in Rust 1.57.
• rust#88582 implements div_floor, div_ceil, next_multiple_of, and checked_next_multiple_of for all integer types.
• rust#88353 partially stabilizes the array_methods feature in Rust 1.57.
• rust#86735 implements RFC 3107, permitting #[derive(Default)] and #[default] on enums.
• rust#86593 partially stabilizes the const_slice_first_last feature in Rust 1.55.
• rust#86592 uses the #[non_exhaustive] attribute where appropriate in the standard library and compiler.
• rust#86213 stabilizes str::from_utf8_unchecked as const fn in Rust 1.55.
• rust#85769 stabilizes the const_fn_transmute and const_fn_union features in Rust 1.55.
• RFC 3107 proposes permitting #[derive(Default)] on enums wherein a unit variant may be tagged with #[default], avoiding the need for a manual implementation.
• rust#83772 modifies the unstable Step trait such that it is no longer unsafe to implement. A new trait, TrustedStep, is added to maintain performance when all invariants are upheld.
• rust#83363 implements a new API for procedural macro diagnostics.
• rust#82130 makes Option::transpose, Option::flatten, and Result::flatten unstably const fn.
• rust#81940 stabilizes str::split_once in Rust 1.52.
• rust#80962 stabilizes 168 inherent implementations on integers as const fn in Rust 1.52.
• rust#80959 stabilizes i*::unsigned_abs() in Rust 1.51.
• rust-analyzer#7215 improves heuristics of hiding parameter inlay hints. rust-analyzer#7224 was submitted as a follow-up for optimization.

quickcheck

• quickcheck#270 eliminates a frequently-encountered panic.

Rocket

• rocket#1143 removes the dependency on the crate_visibility_modifier feature.
• rocket#1129 removes the dependency on the label_break_value feature.
• rocket#1125 uses the BoxFuture type for readability.
• rocket#1124 removes unnecessary boxing.
• rocket#1099 removes the stabilized async_await feature.
• rocket#1097 allows launching on a custom Tokio runtime.
• rocket#1084 uses a proper async fn instead of returning Pin<Box<_>> where possible.
• rocket#1079 implements graceful shutdown functionality, both via signal handling and caller-requested. This was one of the most-requested features in Rocket.
• rocket#1062 removes the unused doc_cfg feature.
• rocket#967 removes the stabilized transpose_result and try_from features.
• rocket#966 removes all uses of the unstable never type (!) in favor of the stable Infallible.

Tokio

• tokio#1492 implements spawn_with_handle on the Tokio executor. This allowed the launching of Rocket on a custom Tokio runtime.
