Struct NumberFormatter

pub struct NumberFormatter(/* private fields */);

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

Implementations

impl NumberFormatter

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.

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.

Trait Implementations

impl Clone for NumberFormatter

fn clone(&self) -> NumberFormatter

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for NumberFormatter

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for NumberFormatter

fn eq(&self, other: &Self) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
