Description

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

Research direction

Start from the log::kv::Value type and the as_serde! call shown in the issue, then trace how a custom logger receives the value. Before coding, establish whether conversion to Vec is intended and what test would define completion, since the issue names no repository file or test.
