Asupersync Rust

Use these conventions for Dicklesworthstone/asupersync, a spec-first async runtime for Rust focused on structured concurrency, explicit capabilities, cancellation protocols, and deterministic testing.

Source Baseline

• Prefer the upstream repository and matching docs over old snippets: https://github.com/Dicklesworthstone/asupersync.
• Baseline checked for this skill: upstream main at bd6e0a3d, package version 0.3.3, Rust edition 2024.
• Asupersync is a 0.x crate and its own src/lib.rs says public items should be treated as unstable unless documented otherwise.
• Current core crate uses nightly-only Rust features such as try_trait_v2; do not present it as stable-toolchain drop-in code.
• Default builds include proc-macros; if default features are disabled, enable proc-macros for scope!, spawn!, join!, join_all!, and race!.

When to Choose It

Choose Asupersync when correctness under cancellation matters more than ecosystem convenience:
