Struct egui::style::NumberFormatter
source · pub struct NumberFormatter(Arc<dyn Sync + Send + Fn(f64, RangeInclusive<usize>) -> String + 'static>);
Expand description
How to format numbers in e.g. a crate::DragValue
.
Tuple Fields§
§0: Arc<dyn Sync + Send + Fn(f64, RangeInclusive<usize>) -> String + 'static>
Implementations§
source§impl NumberFormatter
impl NumberFormatter
sourcepub fn new(
formatter: impl 'static + Sync + Send + Fn(f64, RangeInclusive<usize>) -> String,
) -> Self
pub fn new( formatter: impl 'static + Sync + Send + Fn(f64, RangeInclusive<usize>) -> String, ) -> Self
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.
sourcepub fn format(&self, value: f64, decimals: RangeInclusive<usize>) -> String
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.
