Variants (Non-exhaustive)

This enum is marked as non-exhaustive

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

`Tiny`

A 8 bit signed integer

`UnsignedTiny`

A 8 bit unsigned integer

`Short`

A 16 bit signed integer

`UnsignedShort`

A 16 bit unsigned integer

`Long`

A 32 bit signed integer

`UnsignedLong`

A 32 bit unsigned integer

`LongLong`

A 64 bit signed integer

`UnsignedLongLong`

A 64 bit unsigned integer

`Float`

A 32 bit floating point number

`Double`

A 64 bit floating point number

`Numeric`

A fixed point decimal value

`Time`

A datatype to store a time value

`Date`

A datatype to store a date value

`DateTime`

A datatype containing timestamp values ranging from ‘1000-01-01 00:00:00’ to ‘9999-12-31 23:59:59’.

`Timestamp`

A datatype containing timestamp values ranging from 1970-01-01 00:00:01’ UTC to ‘2038-01-19 03:14:07’ UTC.

`String`

A datatype for string values

`Blob`

A datatype containing binary large objects

`Bit`

A value containing a set of bit’s

`Set`

A user defined set type

`Enum`
