Numbers​

Snapi supports the following number types.

byte​

Minimum value of -128 and a maximum value of 127.

short​

Minimum value of -32768 and a maximum value of 32767.

int​

Minimum value of -2ˆ31 and a maximum value of (2ˆ31)-1.

long​

Minimum value of -32768 and a maximum value of 32767.

float​

As per IEEE 754.

double​

As per IEEE 754.

decimal​

Lossless number representation.

NOTE: Using decimal leads to exact - but very slow - mathematical operations.

Boolean​

bool​

Holds true or false boolean values.

Characters​

string​

Variable length character data.

Temporals​

date​

Calendar date (year, month, day).

Example: 2001-08-22

time​

Time of day (hour, minute, second, millisecond) without a time zone.

Example: 01:02:03.456

timestamp​

Example: 2001-08-22 03:04:05.321

interval​

Span of years, months, weeks, days, minutes, hours, seconds and milliseconds.

Record​

record​

A structure holding multiple named inner types. For example:

{ age: 35, name: "Jane Doe" } // type is record(age: int, name: string)

Collections​

collection​

A structure holding a sequence of items of the same type. The elements are not computed until its contents are consumed.

list​

Similar to collection, but its elements are computed when the list is constructured. Also provides additional operations such as accessing an item by its position/index on the list.

Binary Types​

binary​

A sequence of bytes.

Function​

The function type.

Unknown​

null​

Represents the null type, i.e. an unknown data type.

All values may be nullable. Refer to the section on null handling.
