Stable Features

Provides support and utilities for parsing and handling Rust attributes.

Affects vermouth::attributes…
warnings complete?: Enables emitting diagnostic warnings through the vermouth::Diagnostic API.
complete = attributes, warnings: Enables the complete suite of parsing utilities. This implies every other stable feature except proc-macro2.
proc-macro2: Rewires this crate to build on top of the proc-macro2 crate, instead of the default, officially supported proc_macro crate. This feature should be enabled with caution, and it is considered a major breaking change to do so. Due to the risks of compounding additive features across dependencies, it can be problematic to enable this feature in a library, since it may break other dependencies of this crate.

Enables proc-macro2 >=1, <=1.0.86
unstable-diagnostics-backend: Unstable Features <small><i>(nightly)</i></small>

Enables the proc_macro crate's experimental <a class="stab portability" href="https://github.com/rust-lang/rust/issues/54140"><code>proc_macro_diagnostic</code></a> feature for higher quality diagnostics.
rust-analyzer-hack: enable this in your r-a config
please, please, please do not enable this during compilation.
