Types ¶
type Mutex ¶
type Mutex[T any] struct { // contains filtered or unexported fields }
Mutex creates a type safe mutex wrapper ensuring one cannot access the values of a locked values without first gaining a lock.
func (*Mutex[T]) Lock ¶
func (m *Mutex[T]) Lock() T
Lock locks the Mutex and returns value for use, safe for mutation if
If the lock is already in use, the calling goroutine blocks until the mutex is available.
func (*Mutex[T]) PerformMut ¶
PerformMut safely locks and unlocks the Mutex values and performs the provided function returning its error if one otherwise setting the returned value as the new mutex value.
func (*Mutex[T]) TryLock ¶
TryLock tries to lock Mutex and reports whether it succeeded. If it does the value is returned for use in the Ok result otherwise Err with empty value.
func (*Mutex[T]) Unlock ¶
Unlock unlocks the Mutex accepting a value to set as the new or mutated value. It is optional to pass a new value to be set but NOT required for there reasons: 1. If the internal value is already mutable then no need to set as changes apply as they happen. 2. If there's a failure working with the locked value you may NOT want to set it, but still unlock. 3. Supports locked values that are not mutable.
It is a run-time error if the Mutex is not locked on entry to Unlock.
type Mutex2 ¶ added in v5.15.0
type Mutex2[T any] struct { // contains filtered or unexported fields }
Mutex2 creates a type safe mutex wrapper ensuring one cannot access the values of a locked values without first gaining a lock.
func (Mutex2[T]) Lock ¶ added in v5.15.0
func (m Mutex2[T]) Lock() MutexGuard[T, *sync.Mutex]
Lock locks the Mutex and returns value for use, safe for mutation if
If the lock is already in use, the calling goroutine blocks until the mutex is available.
func (Mutex2[T]) PerformMut ¶ added in v5.15.0
func (m Mutex2[T]) PerformMut(f func(T))
PerformMut safely locks and unlocks the Mutex values and performs the provided function returning its error if one otherwise setting the returned value as the new mutex value.
type MutexGuard ¶ added in v5.15.1
type MutexGuard[T any, M interface{ Unlock() }] struct { // T is the inner generic type of the Mutex T T // contains filtered or unexported fields }
MutexGuard protects the inner contents of a Mutex2 for safety and unlocking.
func (MutexGuard[T, M]) Unlock ¶ added in v5.15.1
func (g MutexGuard[T, M]) Unlock()
Unlock unlocks the Mutex2 value.
type RMutexGuard ¶ added in v5.15.1
type RMutexGuard[T any] struct { // T is the inner generic type of the Mutex T T // contains filtered or unexported fields }
RMutexGuard protects the inner contents of a RWMutex2 for safety and unlocking.
func (RMutexGuard[T]) RUnlock ¶ added in v5.15.1
func (g RMutexGuard[T]) RUnlock()
RUnlock unlocks the RWMutex2 value.
type RWMutex ¶
type RWMutex[T any] struct { // contains filtered or unexported fields }
RWMutex creates a type safe RWMutex wrapper ensuring one cannot access the values of a locked values without first gaining a lock.
func NewRWMutex
deprecated
func (*RWMutex[T]) Lock ¶
func (m *RWMutex[T]) Lock() T
Lock locks the Mutex and returns value for use, safe for mutation if
If the lock is already in use, the calling goroutine blocks until the mutex is available.
func (*RWMutex[T]) Perform ¶
Perform safely locks and unlocks the RWMutex read-only values and performs the provided function.
func (*RWMutex[T]) PerformMut ¶
PerformMut safely locks and unlocks the RWMutex mutable values and performs the provided function.
func (*RWMutex[T]) RLock ¶
func (m *RWMutex[T]) RLock() T
RLock locks the RWMutex for reading and returns the value for read-only use. It should not be used for recursive read locking; a blocked Lock call excludes new readers from acquiring the lock
func (*RWMutex[T]) RUnlock ¶
func (m *RWMutex[T]) RUnlock()
RUnlock undoes a single RLock call; it does not affect other simultaneous readers. It is a run-time error if rw is not locked for reading on entry to RUnlock.
func (*RWMutex[T]) TryLock ¶
TryLock tries to lock RWMutex and returns the value in the Ok result if successful. If it does the value is returned for use in the Ok result otherwise Err with empty value.
func (*RWMutex[T]) TryRLock ¶
TryRLock tries to lock RWMutex for reading and returns the value in the Ok result if successful. If it does the value is returned for use in the Ok result otherwise Err with empty value.
func (*RWMutex[T]) Unlock ¶
Unlock unlocks the Mutex accepting a value to set as the new or mutated value. It is optional to pass a new value to be set but NOT required for there reasons: 1. If the internal value is already mutable then no need to set as changes apply as they happen. 2. If there's a failure working with the locked value you may NOT want to set it, but still unlock. 3. Supports locked values that are not mutable.
It is a run-time error if the Mutex is not locked on entry to Unlock.
type RWMutex2 ¶ added in v5.15.0
type RWMutex2[T any] struct { // contains filtered or unexported fields }
RWMutex2 creates a type safe RWMutex wrapper ensuring one cannot access the values of a locked values without first gaining a lock.
func NewRWMutex2 ¶ added in v5.15.0
NewRWMutex2 creates a new RWMutex for use.
func (RWMutex2[T]) Lock ¶ added in v5.15.0
func (m RWMutex2[T]) Lock() MutexGuard[T, *sync.RWMutex]
Lock locks the Mutex and returns value for use, safe for mutation if
If the lock is already in use, the calling goroutine blocks until the mutex is available.
func (RWMutex2[T]) Perform ¶ added in v5.15.0
func (m RWMutex2[T]) Perform(f func(T))
Perform safely locks and unlocks the RWMutex read-only values and performs the provided function.
func (RWMutex2[T]) PerformMut ¶ added in v5.15.0
func (m RWMutex2[T]) PerformMut(f func(T))
PerformMut safely locks and unlocks the RWMutex mutable values and performs the provided function.
func (RWMutex2[T]) RLock ¶ added in v5.15.0
func (m RWMutex2[T]) RLock() RMutexGuard[T]
RLock locks the RWMutex for reading and returns the value for read-only use. It should not be used for recursive read locking; a blocked Lock call excludes new readers from acquiring the lock
func (RWMutex2[T]) TryLock ¶ added in v5.15.0
TryLock tries to lock RWMutex and returns the value in the Ok result if successful. If it does the value is returned for use in the Ok result otherwise Err with empty value.
func (RWMutex2[T]) TryRLock ¶ added in v5.15.0
func (m RWMutex2[T]) TryRLock() resultext.Result[RMutexGuard[T], struct{}]
TryRLock tries to lock RWMutex for reading and returns the value in the Ok result if successful. If it does the value is returned for use in the Ok result otherwise Err with empty value.
