Lib.rs

sequential is a tiny library that provides with Sequence a sequential number generator that

• produces monotonously increasing integer numbers, starting from a configurable starting point and with a configurable increment
• can be fast-forwarded to skip numbers, but cannot be wound back
• stops producing values when the limit of the chosen type T is reached
• optionally (with feature serde) implements serde's Serialize and Deserialize so that its state can be persisted
• works with all unsigned integers, from u8 to u128, and with usize.
• strictly uses checked_* arithmetics to avoid panic caused by number overflow.

Usage

Add sequential to the dependencies section in your project's Cargo.toml

[dependencies]
sequential = "0.5"

Example

let mut sequence = Sequence::<usize>::new();

assert_eq!(sequence.next(), Some(0_u8));
assert_eq!(sequence.next(), Some(1_u8));

Features

serde (optional)

Adds the serialization and deserialization capability.

Dependencies

The library has no external dependency except the optional one to serde.
