parse_key_value: howto discard stand-alone keys

[tshepang]

$ parse_key_value!("one=1 two=2 three", accept_standalone_key: false)
function call error for "parse_key_value" at (0:67): could not parse whole line successfully

Would be nice to have an option to simply discard three and keep the rest. Is there a workaround?

Hi @tshepang ,

One way to do this would be to use accept_standalone_key: true and then filter the event afterwards to drop any keys that are set to true, though this would result in a false positive if there was a three=true in the string. If you want to open a feature request, we can see about updating parse_key_value to have additional options to ignore non-key/value parts.

That option gives...

function call error for "parse_key_value"...

Would be nice indeed to have additional options for this function.
