Crate pepperflake 

pepperflake

Fast, unforgeable, sortable 64-bit ID generation.

Bit layout (Default)

 63                    20 19           6 5           0
 |------- time (44b) ------|-- rand (14b) -|- check (6b) -|

• 44 bits — millisecond timestamp via CLOCK_REALTIME_COARSE
• 14 bits — xorshift random tail (16,384 slots per ms tick)
• 6 bits — checksum seeded with secret pepper (rejects ~98.4% of fake IDs)

Usage

use pepperflake::{generate, is_valid, configure};

// Optional: Reconfigure bit layout on startup
// configure(12, 8);

let id = generate();
assert!(is_valid(id));

Functions

configure

Adjust the bit allocation for randomness and checksums.

generate

Generate a new ID.

is_valid

Validate an ID.

random_part

Extract the random component of an ID.

set_pepper

Change the secret pepper used for checksums.

timestamp_millis

Extract the Unix epoch timestamp in milliseconds embedded in an ID.
