type Value ​

Value is an atomic value holder, which have internal rwmutex to avoid concurrent writes.

Usage:

// Actually, we have a NewValue() constructor,
// but let's show how to use a Value without it.
val := &Value[int]{}
val.Set(1)
if val.Get() == 1 {
	log.Println("value is 1")
}

type Value[T any] struct {
    // contains filtered or unexported fields
}

func NewValue ​

func NewValue[T any](defaultval T) *Value[T]

NewValue is a constructor of Value, which accepts default value.

func (*Value[T]) Context ​

func (a *Value[T]) Context(c func(value T, set func(value T)))

Context locks value mutex and executes provided function with releasing lock in the end.

func (*Value[T]) Get ​

func (a *Value[T]) Get() T

Get locks value mutex and returns current value.

func (*Value[T]) Set ​

func (a *Value[T]) Set(value T)

Set locks value mutex and sets current value.
