Crate unique_id

A trait and implementations for unique ID generators.

This crate provides three simple traits, starting with Generator. This will return successive unique identifiers. Two implementations of this trait are provided which provide unique string and integer values respectively.

Example

The following shows an example of the StringGenerator implementation.

```rust use uniqueid::Generator; use uniqueid::string::StringGenerator;

let gen = StringGenerator::default(); let mut last = gen.nextid(); for _ in 1..100000 { let next = gen.nextid(); assertne!(last, next); last = next; } ```

Changes

Version 0.1.2

• Added new RandomGenerator implementation.
• Put each implementation into its own feature.
• Added #[inline] to some functions.

Version 0.1.1

• Added trait GeneratorFromSeed and implementation for SequenceGenerator.
• Added benchmark to compare the two current implementations.

Version 0.1.0

• Simple traits Generator, GeneratorWithInvalid, and GeneratorFromStr.
• StringGenerator using UUIDs
• SequenceGenerator using i64

TODO

1. Decide on better FromStr support.
