In non-C languages, it is possible to have ':' in the function names.
It is possible to escape it with backslashes, but if there are too many
backslashes, it is annoying.
This introduce quotation marks (`"` or `'`) support.
For example, without quotes, we have to pass it as below
$ perf probe -x cro3 -L "cro3\:\:cmd\:\:servo\:\:run_show"
<run_show@/work/cro3/src/cmd/servo.rs:0>
0 fn run_show(args: &ArgsShow) -> Result<()> {
1 let list = ServoList::discover()?;
2 let s = list.find_by_serial(&args.servo)?;
3 if args.json {
4 println!("{s}");
With quotes, we can more naturally write the function name as below;
$ perf probe -x cro3 -L \"cro3::cmd::servo::run_show\"
<run_show@/work/cro3/src/cmd/servo.rs:0>
0 fn run_show(args: &ArgsShow) -> Result<()> {
1 let list = ServoList::discover()?;
2 let s = list.find_by_serial(&args.servo)?;
3 if args.json {
4 println!("{s}");
