Struct Range 

pub struct Range {
    pub min: f64,
    pub max: f64,
}

Numeric range with inclusive bounds.

Range is used for axis limits, data bounds, and viewport calculations. The constructor automatically swaps bounds to maintain min <= max.

Fields

min: f64

Minimum value.

max: f64

Maximum value.

Implementations

impl Range

pub fn new(min: f64, max: f64) -> Self

Create a new range, swapping bounds if needed.

pub fn span(&self) -> f64

Span of the range.

pub fn is_finite(&self) -> bool

Check whether both bounds are finite.

pub fn is_valid(&self) -> bool

Check whether the range has positive span and finite bounds.

pub fn expand_to_include(&mut self, value: f64)

Expand the range to include a value.

Non-finite values are ignored.

pub fn union(a: Self, b: Self) -> Option<Self>

Union two ranges if both are finite.

pub fn clamp(&self, value: f64) -> f64

Clamp a value into the range.

pub fn padded(&self, frac: f64, min_padding: f64) -> Self

Add padding around the range.

frac is applied to the current span and clamped by min_padding.

pub fn with_min_span(&self, min_span: f64) -> Self

Ensure the range has at least the given span.

Trait Implementations

impl Clone for Range

fn clone(&self) -> Range

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Range

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

Formats the value using the given formatter.

impl PartialEq for Range

fn eq(&self, other: &Range) -> 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.

impl Copy for Range
