Functions ¶
func BytesFromUUID ¶
BytesFromUUID converts a UUID object to its binary representation as a byte slice. It uses the UUID's MarshalBinary method to get the raw bytes. Optimized version that directly accesses UUID bytes to avoid allocation.
func CastString ¶
func CastString(obj interface{}) *string
CastString attempts to cast an interface{} to a string pointer. Returns a pointer to the string if the cast is successful, nil otherwise.
func IsInt ¶
IsInt checks if a string represents a valid integer. It attempts to parse the string as a 64-bit integer and returns true if successful.
func MaxTimestamp ¶
func MaxTimestamp() int64
MaxTimestamp returns the maximum timestamp value for 32-bit systems (2^32 - 1). This represents the maximum date that can be stored in a 32-bit Unix timestamp.
func MaxTimestamp32u ¶
func MaxTimestamp32u() uint
MaxTimestamp32u returns the maximum timestamp value as an unsigned integer. This is equivalent to MaxTimestamp but returns uint type instead of int64.
func NowUInt ¶
func NowUInt() uint
NowUInt returns the current Unix timestamp as an unsigned integer. This is a convenience function for getting the current time in Unix format.
func SplitRemoteAddr ¶
SplitRemoteAddr parses a network address string and extracts the IP and port components. It handles both IPv4 and IPv6 addresses with proper bracket notation for IPv6. Returns the parsed IP address and port string. If no port is found, port will be empty. Optimized version with reduced string operations and single-pass parsing.
func UnixToTime ¶
UnixToTime converts a Unix timestamp (seconds since epoch) to a time.Time object. The nanosecond component is set to 0.
func ZeroTimestamp ¶
func ZeroTimestamp() int64
ZeroTimestamp returns the zero timestamp value (0) representing the Unix epoch. This is commonly used as a default or initial timestamp value.
