Struct TinyId

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

A tiny 8-byte ID type that is NOT cryptographically secure, but is easy and convenient for tasks that don’t require the utmost security or uniqueness. During lightweight testing, between 1 and 10 million IDs can be generated without any collisions, and performance has been pretty good.

Implementations§

Source§

impl TinyId

Source

pub const LETTER_COUNT: usize = 64usize

The number of letters that make up the potential pool of characters for a TinyId.

Source

pub const LETTERS: [u8; 64]

The letter pool used during generation of a TinyId.

Source

pub const NULL_CHAR: u8 = 0u8

The byte used to represent null data / ids.

Source

pub const NULL_DATA: [u8; 8]

An instance of a fully null byte array, used as the basis for null ids.

Source

pub const fn is_valid_byte(byte: u8) -> bool

Test whether the given byte is valid for use as one of the 8 bytes in a TinyId.

This function exists because I’m tired of writing if LETTERS.contains(&byte) everywhere. Hopefully it is also more efficient to do it this way. Letters (as u8): [45, 48, 49, 50, 51, 52, 53, 54, 55, 56, 57, 65, 66, 67, 68, 69, 70, 71, 72, 73, 74, 75, 76, 77, 78, 79, 80, 81, 82, 83, 84, 85, 86, 87, 88, 89, 90, 95, 97, 98, 99, 100, 101, 102, 103, 104, 105, 106, 107, 108, 109, 110, 111, 112, 113, 114, 115, 116, 117, 118, 119, 120, 121, 122] aka [45, 48..=57, 65..=90, 95, 97..=122]
