Variants

Boolean(bool)

Int8(i8)

Int16(i16)

Int32(i32)

Int64(i64)

Floating32(f32)

Floating64(f64)

Str(String)

Binary(Vec<u8>)

Date((i32, u8, u8))

Time((u8, u8, u8, u32))

(year, month, day)

Datetime((i32, u8, u8, u8, u8, u8, u32))

(hour, minute, second, nanosecond) Date-time types are always treated as UTC (without timezone info). The instant is represented as a (year, month, day, hour, minute, second, nanosecond) tuple.

Timestamp(i64)

Unix timestamp (seconds since epoch)

DbNull
