Components of a snowflake identifier in binary

Snowflake IDs, or snowflakes, are a form of unique identifier used in distributed computing. The format was created by X (formerly Twitter) and is used for the IDs of tweets. It is popularly believed that every snowflake has a unique structure, so they took the name "snowflake ID". The format has been adopted by other companies, including Discord and Instagram. The Mastodon social network uses a modified version.
