CameraFrameNumber

value class CameraFrameNumber

A strongly typed identifier for a camera frame.

A frame number is a unique, monotonically increasing identifier assigned to each frame produced by a camera device. Wrapping this in a value class prevents type confusion with other Long identifiers (such as timestamps, request IDs, or camera IDs) and enforces type safety at compile time.

As a JvmInline value class, it has zero runtime overhead when compiled, as the compiler replaces instances of this class with the underlying Long value where possible.

Example

val frameNumber = CameraFrameNumber(42L)
println(frameNumber.value) // Prints: 42
println(frameNumber)       // Prints: Frame-42
