Functions ¶

func SafeIntToUint16 ¶

func SafeIntToUint16(v int) uint16

SafeIntToUint16 converts int to uint16 with overflow check.

func SafeIntToUint32 ¶

func SafeIntToUint32(v int) uint32

SafeIntToUint32 converts int to uint32 with overflow check.

func SafeIntToUint8 ¶

func SafeIntToUint8(v int) uint8

SafeIntToUint8 converts int to uint8 with overflow check.

func SafeUintToInt ¶

func SafeUintToInt(v uint) int

SafeUintToInt converts uint to int with overflow check.

func StrToBool ¶ added in v0.5.0

func StrToBool(str string) (bool, error)

StrToBool converts a string to bool considering various truthy representations. Accepts: "true", "yes", "y", "on", "1", "t" as true Accepts: "false", "no", "n", "off", "0", "f" as false Returns error for empty strings or unrecognized values.

Types ¶

type TTLCache ¶ added in v0.10.1

type TTLCache[V any] struct {
	// contains filtered or unexported fields
}

TTLCache is a simple in-memory cache with time-to-live expiration. Expired entries are removed lazily during Get and Set operations.

func NewTTLCache ¶ added in v0.10.1

func NewTTLCache[V any](ttl time.Duration) *TTLCache[V]

NewTTLCache creates a cache with the specified TTL for all entries.

func (*TTLCache[V]) Clear ¶ added in v0.10.1

func (c *TTLCache[V]) Clear()

Clear removes all entries from the cache.

func (*TTLCache[V]) Delete ¶ added in v0.10.1

func (c *TTLCache[V]) Delete(key string)

Delete removes an entry from the cache.

func (*TTLCache[V]) Get ¶ added in v0.10.1

func (c *TTLCache[V]) Get(key string) (V, bool)

Get retrieves a value if it exists and hasn't expired. Returns the value and true if found and valid, zero value and false otherwise.

func (*TTLCache[V]) Len ¶ added in v0.10.1

func (c *TTLCache[V]) Len() int

Len returns the number of entries in the cache (including expired ones).

func (*TTLCache[V]) Set ¶ added in v0.10.1

func (c *TTLCache[V]) Set(key string, value V)

Set stores a value with the cache's default TTL.
