Protocols

The TimeIntervalLiterals protocol is used to extend IntegerLiteralType and FloatLiteralType to allow for human-readable time notations such as:

let sixtySeconds = 60.seconds
let twoAndAHalfMinutes = 2.5.minutes
let oneWeek = 7.days
let anotherWeek = 1.week

Default implementations of the minutes, hours, days, and weeks properties are supplied; implementors of the TimeIntervalLiterals protocol only need to supply an implementation for seconds.
