PatcherDefinition

Build Patcher using current configuration.

It runs macro that tries to derive instance of Patcher[A, Patch]. When transformation can't be derived, it results with compilation error.

Then there scala.Option is patching scala.Option, on scala.None value will be cleared.

Disable printing the logs from the derivation process.

Enable printing the logs from the derivation process.

Fail the compilation if there is a redundant field in patching object.

In case when both object to patch and patch value contain field of type scala.Option, this option allows to treat scala.None value in patch as if the value was not provided.

By default, when scala.None is delivered in patch, Chimney clears the value of such field on patching.

In case that patch object contains a redundant field (i.e. field that is not present in patched object type), this option enables ignoring value of such fields and generate patch successfully.

By default, when Chimney detects a redundant field in patch object, it fails the compilation in order to prevent silent oversight of field name typos.
