Conversion from log::kv::Value to Option<Vec<String>>

[lcmgh]

Hello!

I am implementing a custom logger that prints a JSON serialized struct. The struct has a field custom_list: Option<Vec<String>> that should be derived from log::kv::Value. However I could not figure out how to convert to Vec<String> from Value? Is that a missing feature or am I overseeing something here?

MyStruct {
   custom_list: Option<Vec<String>>
}

From end users perspective:
info!(custom_list = as_serde!(vec!["a".to_string(), "b".to_string()]); "Test log msg");

Thanks

This is quite a useful thing to be able to do, and is currently a feature gap in log. The underlying library that supports log::kv::Value did just recently get some support for pulling sequences from values: https://docs.rs/value-bag/latest/value_bag/struct.ValueBag.html#method.to_str_seq.

We could try come up with an API that makes sense for log::kv::Value too.
