Struct Semantic64

pub struct Semantic64<K> { /* private fields */ }

Semantic64<K> is a struct that contains a 64-bit integer ID. This ID is composed of the following parts:

• 48-bit millisecond timestamp: Used to represent the time when the ID was created. The timestamp range starts from January 1, 1970, 00:00:00 UTC, and can represent approximately 279,000 years.
• 8-bit device ID: Used to identify the device or service instance that created the ID. It can represent up to 256 different devices.
• 8-bit sequential ID: Used to generate multiple IDs within a 1-millisecond interval. It can represent a sequential ID between 0 and 255.

This ID structure can guarantee uniqueness in a distributed system, while also providing time and device information. It is suitable for scenarios that require generating unique IDs, such as message IDs, event IDs, and so on.
