Fixes #381
This PR introduces a new
MapField
type, which can be used to set and access map field values by key.Without this PR I get a panic in
toStarlark1
wherex.Message()
is called on a map field value. (Perhaps because my proto has somemap<string, Message>
fields):I've also updated the nascent
proto.star
unit tests to use their own proto file, to test repeated and map fields.Separately from the main change, I've included a commit that adds a list-like
append
method toRepeatedField
. I can break that out into a separate PR if you'd prefer.
