Struct nuid::NUID

pub struct NUID { /* private fields */ }

NUID needs to be very fast to generate and truly unique, all while being entropy pool friendly. We will use 12 bytes of crypto generated data (entropy draining), and 10 bytes of sequential data that is started at a pseudo random number and increments with a pseudo-random increment. Total is 22 bytes of base 62 ascii text :)

Implementations

impl NUID

pub fn new() -> Self

generate a new NUID and properly initialize the prefix, sequential start, and sequential increment.

pub fn randomize_prefix(&mut self)

pub fn next(&mut self) -> String

Generate the next NUID string.

pub fn next_into(&mut self, buffer: &mut [u8; 22])

Generate the next NUID into a byte array.

All generated bytes are valid ASCII characters in [0-9A-Za-z].

Trait Implementations

impl Default for NUID

fn default() -> Self

Returns the “default value” for a type.
