Struct ProgressBarRangeInfo 

pub struct ProgressBarRangeInfo {
    pub current: f32,
    pub start: f32,
    pub end: f32,
    pub steps: u32,
}

The value a control holds inside a range, for a slider, a dial or a progress bar.

This is Compose’s ProgressBarRangeInfo (Modifier.progressSemantics(value, range, steps)). A control without it reads as plain text: a screen reader user hears “47 percent” and has no way to change it, because nothing tells the platform the control is adjustable.

Fields

current: f32

start: f32

end: f32

steps: u32

How many stops sit between start and end, as Compose counts them. Zero means the value moves without stops.

Implementations

impl ProgressBarRangeInfo

pub fn new( current: f32, start: f32, end: f32, steps: u32, ) -> ProgressBarRangeInfo

pub fn fraction(&self) -> f32

Where the value sits between the two ends, from 0 to 1.

pub fn step(&self) -> f32

How far one stop moves the value. With no stops, one tenth of the range, which is what a screen reader’s swipe up and down expects.
