rust-core-language-versions
Ecosystem identity skill for Rust : editions, channels, MSRV, version matrix. This is the conceptual map. For toolchain mechanics (rustup, cargo, rustc flags) see [[rust-core-toolchain]]. For edition-2024 syntactic changes see [[rust-syntax-edition-2024]]. For Cargo.toml details including [lints] and rust-version mechanics see [[rust-impl-cargo-project]].
Quick Reference
Identity in one paragraph
Rust is a statically-typed, ahead-of-time-compiled systems language. No garbage collector. Memory safety enforced by ownership at compile time. Zero-cost abstractions via monomorphization. Six-week release cadence on the stable channel. Editions (2015, 2018, 2021, 2024) gate opt-in language evolution without breaking older crates. Current stable target for this skill package : Rust 1.85+, edition 2024.
Channel matrix
| Channel | Cadence | Purpose | Use when |
|---|---|---|---|
| stable | 6 weeks | Production | ALWAYS for shipping code |
| beta | 6 weeks | Last-mile stabilization candidate | Verifying your crate before a Rust release |
| nightly | Daily | New unstable features | A required feature is #![feature(...)]-gated |
