Struct RangeValue 

pub struct RangeValue {
    pub lower: Option<f64>,
    pub upper: Option<f64>,
}

Range value for numeric ranges (lower and upper bounds, both optional).

Used in Value::VRange to represent numeric ranges with optional bounds.

Note: This type only implements PartialEq, not Eq, because f64 doesn’t implement Eq (due to NaN != NaN).

Examples

use pattern_core::RangeValue;

// Closed range: 1.0 to 10.0
let range1 = RangeValue {
    lower: Some(1.0),
    upper: Some(10.0),
};

// Lower bound only: 1.0 to infinity
let range2 = RangeValue {
    lower: Some(1.0),
    upper: None,
};

// Upper bound only: negative infinity to 10.0
let range3 = RangeValue {
    lower: None,
    upper: Some(10.0),
};

Fields

lower: Option<f64>

Lower bound of the range (inclusive), None means unbounded below

upper: Option<f64>

Upper bound of the range (inclusive), None means unbounded above

Trait Implementations

impl Clone for RangeValue

fn clone(&self) -> RangeValue

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for RangeValue

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

Formats the value using the given formatter.

impl Display for RangeValue

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

Formats the value using the given formatter.

impl PartialEq for RangeValue

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