Types ¶
type Attributes ¶
type Attributes struct {
// contains filtered or unexported fields
}
Attributes is an immutable struct for storing and retrieving generic key/value pairs. Keys must be hashable, and users should define their own types for keys.
func New ¶
func New(kvs ...interface{}) *Attributes
New returns a new Attributes containing all key/value pairs in kvs. If the same key appears multiple times, the last value overwrites all previous values for that key. Panics if len(kvs) is not even.
func (*Attributes) For ¶
func (a *Attributes) For(call func(key interface{}, val interface{}))
func (*Attributes) Value ¶
func (a *Attributes) Value(key interface{}) interface{}
Value returns the value associated with these attributes for key, or nil if no value is associated with key.
func (*Attributes) WithValues ¶
func (a *Attributes) WithValues(kvs ...interface{}) *Attributes
WithValues returns a new Attributes containing all key/value pairs in a and kvs. Panics if len(kvs) is not even. If the same key appears multiple times, the last value overwrites all previous values for that key. To remove an existing key, use a nil value.
