Rust 1.95.0 arrived yesterday via rustup update stable<\/code>. Two features stand out for everyday Rust development, plus one change worth noting if you work on non-standard platforms.<\/p>\n\n\n\n

Fewer External Dependencies for Platform-Specific Code<\/h2>\n\n\n\n

The new cfg_select!<\/code> macro lets you choose different code blocks based on target platform or compilation flags, using syntax similar to a regular match<\/code> statement. Until now, the go-to solution was the cfg-if<\/code> crate, widely used across projects. With Rust 1.95, this functionality moves into the standard library, eliminating the external dependency.<\/p>\n\n\n\n

If-Let Guards in Match Expressions<\/h2>\n\n\n\n

Rust 1.88 introduced let chains<\/em>, allowing you to chain multiple let<\/code> conditions in a single if<\/code> or while<\/code> expression. Rust 1.95 extends this to match statements: you can now add an if let<\/code> condition directly on a match arm, combining pattern matching and a secondary value check in one go. For anyone working with complex data structures or optional results, this means cleaner code without splitting logic across multiple steps.<\/p>\n\n\n\n

Note for Embedded Developers<\/h2>\n\n\n\n

Rust 1.95 removes support for JSON-based custom target specifications from the stable release. These are mainly used in embedded development for unofficially supported platforms. As the Rust team explains, this feature already required the nightly channel, so stable-only users shouldn’t notice anything. The team opened an issue to gather real-world use cases before deciding whether and how to stabilize something down the road.<\/p>\n\n\n\n \n
