Crate use_bar 

use-bar

Primitive OHLC and OHLCV bar vocabulary for RustUse quantitative crates.

use-bar describes bars with simple labels, intervals, prices, and optional volume. It validates obvious OHLC relationships without fetching, resampling, charting, or storing market data externally.

Example

use use_bar::{BarInterval, BarTime, OhlcvBar};

let bar = OhlcvBar::from_values(
    BarTime::new("2026-05-17")?,
    BarInterval::Day,
    100.0,
    102.0,
    99.5,
    101.25,
    42_000.0,
)?;

assert_eq!(bar.bar().close().value(), 101.25);
assert_eq!(bar.volume(), 42_000.0);

Scope
