The class, struct, union, record, and enum types come under aggregate types. The record type is one of them, it can have n number of members of any individual type. Record type members are by default immutable but we can make them mutable. In general, a record type uses the members as an immutable data type. There is no way to execute logic during instantiation as a record type don't have constructors. A record type also supports match expression, depending on the values inside those records, and they can also again decompose those values for individual handling, for example:
type Box = {width: float ; height:int }let giftbox = {width = 6.2 ; height = 3 }
In the previous example, we declared a Box with float a value width and ...
