// Diagnostic: unresolved-proc-macro
//
// This diagnostic is shown when a procedural macro can not be found. This usually means that
// procedural macro support is simply disabled (and hence is only a weak hint instead of an error),
// but can also indicate project setup problems.
//
// If you are seeing a lot of "proc macro not expanded" warnings, you can add this option to the
// `rust-analyzer.diagnostics.disabled` list to prevent them from showing. Alternatively you can
// enable support for procedural macros (see `rust-analyzer.procMacro.enable`).
