Struct CountUp 

pub struct CountUp { /* private fields */ }

A number that counts up from zero to its value when it first shows on screen, and from where it is to its new value whenever the value changes, even halfway through a count. Its digits keep one width, so the number does not shake as it counts. Under reduced motion it shows the value at once.

Implementations

impl CountUp

pub fn new(value: f64) -> Self

Counts up to value, shown as a whole number with thousands separators.

pub fn format(self, format: impl Fn(f64) -> String + 'static) -> Self

How each step of the count is written, such as |v| format!("{v:.0}+").

pub fn style(self, style: TextStyle) -> Self

The text style (metric by default).

pub fn seconds(self, seconds: f64) -> Self

How long a count takes (1.5 seconds by default).

pub fn easing(self, easing: Easing) -> Self

The pace of the count (fast, then settling, by default).

pub fn start_at_value(self) -> Self

Shows its value from the start: only later changes count, as for a figure on a dashboard that follows a filter.
