Description
rust-analyzer version: 0.3.2803-standalone
rustc version: 1.93.0
editor or extension: VSCode extension version 0.3.2803
relevant settings: none?
repository link (if public, optional): https://github.com/x-hgg-x/custom-format
code snippet to reproduce:
fn main() {
custom_format::println!("hello");
}
Produces "invalid tokens" macro error in rust-analyzer whenever pretty much any of the macros from custom_format are used, even in trivial examples like the above. The compiler is fine with it.

Research direction
Start with the provided main function and the custom_format::println!("hello") invocation, then compare rust-analyzer's "invalid tokens" diagnostic with rustc's successful compilation. Reproduce the issue across the custom-format macros mentioned in the report; done means rust-analyzer no longer reports the false macro error while compiler behavior remains unchanged.
