Types ¶

type Mask ¶

type Mask uint8

A Mask is a bitmask of reserved, widely used, no-valued attributes whose presence in a Set is the indicator. All eight bits may be set; their semantics are defined by the user of this package.

type Set ¶

type Set struct {
	// Mask is a bitmask that may be manipulated directly.
	// See the Mask type doc for details.
	Mask Mask
	// contains filtered or unexported fields
}

Set is a collection of attributes, represented as a Mask and a map of arbitrary uint8 keys to string values.

The zero value of Set is an empty, default set.

func (Set) Clone ¶

func (s Set) Clone() Set

Clone returns a clone of the given Set.

func (Set) Compare ¶

func (s Set) Compare(other Set) int

Compare returns -1, 0 or 1 depending on whether the Set is ordered before, equal to or after the other Set.

func (Set) ForEachAttr ¶

func (s Set) ForEachAttr(f func(key uint8, value string))

ForEachAttr calls f for each attribute in ascending key order.

func (Set) GetAttr ¶

func (s Set) GetAttr(key uint8) (value string, ok bool)

GetAttr gets an attribute from the Set.

func (Set) IsRegular ¶

func (s Set) IsRegular() bool

IsRegular reports whether the Set is equivalent to its zero value.

func (*Set) SetAttr ¶

func (s *Set) SetAttr(key uint8, value string)

SetAttr adds an attribute to the Set, replacing any existing one of the same key. Keys >= 64 aren't supported yet, and will cause a panic.
