    Parameters

    json

    The value in its associated JSONType
    owner

    Optional, the owning element
    context

    An in-out parameter for the instantiation context

  • Declaration

Protocols

  • Undocumented

    Declaration

    Swift

Equatable, Comparable

  • Declaration

    Swift

    public static func ==(lhs: Instant, rhs: Instant) -> Bool

    Parameters

    A value to compare.
    rhs

    Another value to compare.

  • Declaration

    Swift

    public static func <(lhs: Instant, rhs: Instant) -> Bool

    Parameters

    lhs

    A value to compare.
    rhs

    Another value to compare.

  • Attempts to parse an Instant from RFC1123-formatted date strings, usually used by HTTP headers:

    • EEE’,’ dd MMM yyyy HH’:‘mm’:‘ss z
    • EEEE’,’ dd’-'MMM’-'yy HH’:'mm’:'ss z (RFC850)
    • EEE MMM d HH’:'mm’:'ss yyyy

    Declaration

    Swift

    public static func fromHttpDate(_ httpDate: String) -> Instant?

    Parameters

    httpDate

    The date string to parse
