Support --message-format=json for inline IDE hints with Rust Analyzer #571
Description
Activity
I see this issue being in the same bucket as
cargo gpu clippycannot pass--fixRust-GPU/rust-gpu#570: You can't pass ordinary arguments throughcargo gpu.Which is why I'd like to refactor the argument parsing of cargo-gpu to go from "everything can be passed as args" to "everything has to be configured in the
Cargo.tomlin the shader crate" and we parse (almost?) no args at all. Just forward all args to the underlying cargo implementation of<subcommand>, instead of reimplementing every single arg ourselves.There's still a few people relying on passing cargo-gpu configuration via cmdline, so it'll be a breaking change for them, but I do think it's a necessity.

Being able to pass
--message-format=jsonwould allow us to specifycargo gpu check --message-format=jsonas a check command and then the Rust Analyzer plugin would be able to read the output of this and show the errors and warnings within the IDE as underlines. This would be very useful for development.
