Overview ¶
Package datepart is the one reading of ATTR_DATE_PART's params and field, shared by the operator factory (internal/processing) and predict (internal/descriptor) so both refuse the same request with the same code and message. It decides what a request MEANS and never extracts a value: the calendar arithmetic lives in internal/temporal.
Leaf: stdlib, the public errors / encoding / types packages and the accepted-types table (internal/fieldaccept, itself a leaf).

Functions ¶
func CheckField ¶
CheckField judges the schema field f (nil: absent from the schema) that part reads from field. A `date` or `datetime` is accepted, except that `hour` needs a `datetime` (a calendar date carries no time of day, so every row would read hour 0). Any other type is the accepted-types table's PULSE_FIELD_TYPE_UNSUPPORTED (as is a date under `hour`); an absent field is PROCESSING_CONFIG.
