Hey @pkwarren Sorry to bug but is there any chance you could maybe have a look at this PR and let me know if this is an addition that would be welcome? Thanks in advance! |

Hey @boekkooi-impossiblecloud, thanks for the PR! I have some questions over here: #109 (comment) |
This allows for later usage of the fieldProperty name.
Ran `make lint` and resolved warnings/errors.

is this an invariant from the generator? or should we at least print the actual type of r in the case of an error?
The anyOf approach explodes the resultant jsonschema, and also contains
a bug. In the earlier code, a oneof a/b/c would generate:
{"required": ["a"], "not": {"required": ["b", "c"]}}
This means `b` and `c` can't be together, but `a` and `b` can.
This rule can name fields without presence, which means the jsonschema must reflect that at most one of the fields can be set to their non-zero value. This is doable, but requires a separate discussion.

Good day,
While I was using the
protoc-gen-jsonschemaand it's generated schemas I noticed that oneOf validation was not happening for the on the JSON schema level.This PR implements the protobuf oneOf functionality and
(buf.validate.message).oneofusing the JSON Schema allOf and anyOf by using not in combination with required to exclude all other fields except for the one needed.Thanks for reviewing this PR! Please let me know what you think and have a great day!
