//! Convenience functions for formatting and parsing parameter values in common formats.

use std::sync::Arc;

/// Round an `f32` value to always have a specific number of decimal digits.
pub fn f32_rounded(digits: usize) -> Option<Arc<dyn Fn(f32) -> String + Send + Sync>> {
    Some(Arc::new(move |x| format!("{:.digits$}", x)))
}
Add a simple formatters library We can add common formats here so you don't need to repeat them all the time. 2022-01-29 00:33:29 +11:00			`//! Convenience functions for formatting and parsing parameter values in common formats.`

Use Arcs for the callbacks So it becomes possible to reuse one callback for multiple parameters. This will be important for value change notifications. 2022-02-01 06:44:10 +11:00			`use std::sync::Arc;`
