|

|
|
Напишите примитив синхронизации, позволяющий "лочить" строки из множества.
|
||
|
|
|
||
|
|
```go
|
||
|
|
package keylock
|
||
|
|
|
||
|
|
type KeyLock interface {
|
||
|
|
// LockKeys locks all keys from provided set.
|
||
|
|
//
|
||
|
|
// Upon successful completion, function guarantees that no other call with intersecting set of keys
|
||
|
|
// will finish, until unlock() is called.
|
||
|
|
//
|
||
|
|
// If cancel channel is closed, function returns immediately.
|
||
|
|
LockKeys(keys []string, cancel <-chan struct{}) (canceled bool, unlock func())
|
||
|
|
}
|
||
|
|
```
