SnowflakeIdGenerator

rust_mcp_extra::id_generator

Struct SnowflakeIdGenerator 

Source 
pub struct SnowflakeIdGenerator { /* private fields */ }
Expand description

A Snowflake ID generator implementation producing 64-bit unique IDs.

Snowflake IDs are composed of:

  • A timestamp in milliseconds since a custom epoch (usually a fixed past time),
  • A machine ID (or worker ID) to differentiate between nodes,
  • A sequence number that increments within the same millisecond to avoid collisions.

Format (64 bits total):

  • 41 bits: timestamp (ms since SHORTER_EPOCH)
  • 10 bits: machine ID (0-1023)
  • 12 bits: sequence number (per ms)

This generator ensures:

  • Uniqueness across multiple machines (given unique machine IDs),
  • Monotonic increasing IDs when generated in the same process,
  • Thread safety with internal locking.
