I see that we have rust_analyzer_run_single to do a rust-analyzer.runSingle.

To do something like rust_analyzer_debug_single, rather than simply cargo ${cargoArgs} ${cargoExtraArgs} -- ${executableArgs} a debug_single for rust would do something like following:

• if cargoArgs[0] == "test", shell out cargo test --no-run --message-format=json -q ${cargoArgs} ${cargoExtraArgs}
• if cargoArgs[0] == "run", shell out cargo build --message-format=json -q ${cargoArgs} ${cargoExtraArgs}
• Parse the output json to Then use something like termDebug or vimspector. It seems like there's a need for an external dependency.

coc-rust-analyzer does something similar.

Anyway, I looked into this a bunch and but I my vimscript is pretty weak/in-existent so I figured I'd write an issue before doing it.

Is there interest in this addition?
