Struct rerun::external::eframe::egui::style::NumberFormatter

pub struct NumberFormatter(Arc<dyn Fn(f64, RangeInclusive<usize>) -> String + Sync + Send>);
Expand description

How to format numbers in e.g. a crate::DragValue.

Tuple Fields§

§0: Arc<dyn Fn(f64, RangeInclusive<usize>) -> String + Sync + Send>

Implementations§

§

impl NumberFormatter

pub fn new( formatter: impl Sync + Send + Fn(f64, RangeInclusive<usize>) -> String + 'static ) -> NumberFormatter

The first argument is the number to be formatted. The second argument is the range of the number of decimals to show.

See Self::format for the meaning of the decimals argument.

pub fn format(&self, value: f64, decimals: RangeInclusive<usize>) -> String

Format the given number with the given number of decimals.

Decimals are counted after the decimal point.

The minimum number of decimals is usually automatically calculated from the sensitivity of the crate::DragValue and will usually be respected (e.g. include trailing zeroes), but if the given value requires more decimals to represent accurately, more decimals will be shown, up to the given max.
