[求助] 如何使用dap-mode对rust的单元测试进行debug ?

dap-mode的文档对我来说太简略了, 配了半天勉强可以对rust bin(就是整个可执行文件)进行debug, 但如何实现类似clion/vscode中对单独测试的调试? 我搜索了一下似乎没看到相关信息, 还请麻烦各位前辈指教. :pray:

暂时糊了一个脚本凑合用一下, 要是有更好的方案请各位大佬指出… 我是emacs新手, 很多东西还搞不清楚… ( 依赖 rustic 和 realgud )

(defun rust-my-debugger ()
  "debugging unit test near point."
  (interactive)
  (let*((test-target (format "%s" (rustic-cargo--get-test-target)) )
        )
        (realgud:gdb  (format "rust-debugger -t %s" test-target) nil)
    )
  )

调用rust-gdb的脚本: rust-debugger (依赖rustup)

#!/bin/bash

debugger=rust-gdb
gdbtmp=/tmp/gdbscript
binary=`cargo test --no-run 2>&1 >/dev/null | grep Executable | cut -d  '('  -f2|cut -d  ')'  -f1 `
used_rustc="/rustc/"`rustc -Vv | grep commit-hash | cut -d' ' -f 2`
tool=`rustup toolchain list | grep '(default)' | cut -d' ' -f 1`
source_code="${HOME}/.rustup/toolchains/${tool}/lib/rustlib/src/rust" 

while getopts t: opt
do
    case "${opt}" in
          t) name=${OPTARG};;
    esac
done

echo "set filename-display absolute" > ${gdbtmp} 
echo "set substitute-path  ${used_rustc}  ${source_code}" >> ${gdbtmp}

if [ ! -n "${name}" ]; then
echo "no testname"
else
echo "b ${name}" >> ${gdbtmp}
echo "run --test ${name}" >> ${gdbtmp}
fi

${debugger} ${binary}  -x ${gdbtmp}
