The sparklines crate provides a simple way to generate sparklines.

Sparklines

A Rust library for Sparklines.

Implementations

Sparklines exposes two indexer implementations:

• Algorithmic – computes the tick index using a simple formula.
• Rangemap – uses a range map to determine which tick to use.

use sparklines::{AlgorithmicSpark, RangemapSpark};

let a = AlgorithmicSpark::default();
let r = RangemapSpark::default();

assert_eq!(a.spark(&[1.0, 2.0, 3.0]), "▁▅█");
assert_eq!(r.spark(&[1.0, 2.0, 3.0]), "▁▄█");
