Register string extension functions to match pv-go#439
Merged
Conversation
Currently, protovalidate-java doesn't register the same string extension functions at protovalidate-go, making custom CEL rules not supported across platforms. Register the CEL string extension functions available in cel-java. These are identical to the ones available in protovalidate-go except it is missing a `quote` and `reverse` function. We could implement custom versions but it would be better to get this addressed upstream for consistency across CEL runtimes. Fixes #438.
