- Language updates * Basic procedural macros allowing custom `#[derive]`, aka "macros 1.1", are stable. This allows popular code-generating crates like Serde and Diesel to work ergonomically. [RFC 1681]. * [Tuple structs may be empty. Unary and empty tuple structs may be instantiated with curly braces][36868]. Part of [RFC 1506]. * [A number of minor changes to name resolution have been activated][37127]. They add up to more consistent semantics, allowing for future evolution of Rust macros. Specified in [RFC 1560], see its section on ["changes"] for details of what is different. The breaking changes here have been transitioned through the [`legacy_imports`] lint since 1.14, with no known regressions. * [In `macro_rules`, `path` fragments can now be parsed as type parameter bounds][38279] * [`?Sized` can be used in `where` clauses][37791] * [There is now a limit on the size of monomorphized types and it can be modified with the `#![type_size_limit]` crate attribute, similarly to the `#![recursion_limit]` attribute][37789] - Compiler changes * [On Windows, the compiler will apply dllimport attributes when linking to extern functions][37973]. Additional attributes and flags can control which library kind is linked and its name. [RFC 1717]. * [Rust-ABI symbols are no longer exported from cdylibs][38117] * [The `--test` flag works with procedural macro crates][38107] * [Fix `extern "aapcs" fn` ABI][37814] * [The `-C no-stack-check` flag is deprecated][37636]. It does nothing. * [The `format!` expander recognizes incorrect `printf` and shell-style formatting directives and suggests the correct format][37613]. * [Only report one error for all unused imports in an import list][37456] - Compiler performance OBS-URL: https://build.opensuse.org/package/show/devel:languages:rust/rust?expand=0&rev=35
