Struct ThumbBounds 

pub struct ThumbBounds { /* private fields */ }

How short and how long a thumb may get, as fractions of the track.

A very long list would otherwise produce a thumb too small to see or to grab; a platform states its own floor rather than inheriting someone else’s.

Implementations

impl ThumbBounds

pub const FULL: Self

A thumb free to be any length, which is what a caller that enforces a minimum in pixels rather than fractions wants.

pub fn new(minimum: f32, maximum: f32) -> Self

Bounds clamped into 0..=1 and ordered, so a caller cannot describe an empty range.

pub fn at_least(extent: f32, track: f32) -> Self

The bounds that keep a thumb at least extent long on a track of track — the pixel-shaped way to say it.

pub fn minimum(self) -> f32

Shortest permitted thumb, as a fraction of the track.

pub fn maximum(self) -> f32

Longest permitted thumb, as a fraction of the track.
