GoIota


Introduction

Iota provides a way of declaring numeric constants from a starting value that grows monotonically. Iota can be used to declare bitmasks which are often used in system and network programming and other lists of constants with related values.

Remarks

The iota identifier is used to assign values to lists of constants. When iota is used in a list it starts with a value of zero, and increments by one for each value in the list of constants and is reset on each const keyword. Unlike the enumerations of other languages, iota can be used in expressions (eg. iota + 1) which allows for greater flexibility.
