Types

type Cache added in v1.8.1 

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

Cache is a generic implementation of a cache that can be configured with a maximum number of items and can evict items after a certain amount of time.

func NewCache added in v1.8.1 

func NewCache[T any](
	expireAfter, checkExpireInterval time.Duration,
	maxItems int) *Cache[T]

NewCache initializes a new cache with the provided expiration options.

func (*Cache[T]) Close added in v1.8.1 

func (c *Cache[T]) Close()

Close shuts down the cache. It is safe to call this function more than once.

func (*Cache[T]) Delete added in v1.8.1 

func (c *Cache[T]) Delete(id string)

Delete removes the specified item from the cache.

func (*Cache[T]) ExpiredChan added in v1.8.1 

func (c *Cache[T]) ExpiredChan() <-chan string

ExpiredChan returns a channel on which the IDs of items that are expired are sent. This channel is closed when the cache is closed, but only after all, pending eviction notices are received.

func (*Cache[T]) Get added in v1.8.1 

func (c *Cache[T]) Get(id string, isHit func(t T) bool) (T, bool)

Get returns the cached item with the provided ID. The function isHit may be optionally provided to further determine whether a cached item should hit or miss.

func (*Cache[T]) Put added in v1.8.1 

func (c *Cache[T]) Put(id string, t T) CachePutResult

Put stores the provided item in the cache, updating existing items.

type CacheItem added in v1.8.1 

type CacheItem[T any] struct {
	// Item is the cached item.
	Item T

	// LastUpdated is the last time the item was updated.
	LastUpdated time.Time
}

CacheItem wraps T so it has a LastUpdated field and can be used with Cache.

type CachePutResult added in v1.8.1 

type CachePutResult uint

CachePutResult describes the result of putting an item into the cache. 

const (
	// CachePutResultCreate indicates the item was created in the cache.
	CachePutResultCreate CachePutResult = iota + 1

	// CachePutResultUpdate indicates an existing, cached item was updated.
	CachePutResultUpdate

	// CachePutResultMaxItemsExceeded indicates the item was not stored because
	// the cache's maximum number of items would have been exceeded.
	CachePutResultMaxItemsExceeded
)

type LockPool added in v1.8.1 

type LockPool[K any, V sync.Locker] struct {
	// contains filtered or unexported fields
}

LockPool is a synchronized set of maps that can be obtained with a provided ID.

func (*LockPool[K, V]) Delete added in v1.8.1 

func (p *LockPool[K, V]) Delete(id K)

Delete removes the specified lock from the pool.

func (*LockPool[K, V]) Get added in v1.8.1 

func (p *LockPool[K, V]) Get(id K) sync.Locker

Get returns the lock for the provided ID.

type SelectDeviceFn 

type SelectDeviceFn[T vimTypes.BaseVirtualDevice] func(dev vimTypes.BaseVirtualDevice) bool
