nullable

nullable is a library with reasonable options for dealing with nullable SQL and JSON values

Types in nullable will only be considered null on null input, and will JSON encode to null. If you need zero and null be considered separate values, use these.

All types implement: encoding.TextMarshaler, encoding.TextUnmarshaler, json.Marshaler, and json.Unmarshaler. A null object's MarshalText will return a blank string.

nullable.String

Nullable string.

Marshals to JSON null if SQL source data is null. Zero (blank) input will not produce a null String.

nullable.Int64

Nullable int64.

Marshals to JSON null if SQL source data is null. Zero input will not produce a null Int64.

nullable.Int32

Nullable int32.

Marshals to JSON null if SQL source data is null. Zero input will not produce a null Int32.

nullable.Float

Nullable float64.

Marshals to JSON null if SQL source data is null. Zero input will not produce a null Float.

nullable.Bool

Nullable bool.

Marshals to JSON null if SQL source data is null. False input will not produce a null Bool.
