pub enum FieldRepetitionType {
REQUIRED = 0,
OPTIONAL = 1,
REPEATED = 2,
}Expand description
Representation of field types in schema.
Variants§
REQUIRED = 0
This field is required (can not be null) and each row has exactly 1 value.
OPTIONAL = 1
The field is optional (can be null) and each row has 0 or 1 values.
REPEATED = 2
The field is repeated and can contain 0 or more values.
