Struct RelativeScalar 

pub struct RelativeScalar {
    pub scalar: f64,
    pub unit: RelativeUnit,
}

Defines a scalar that may be defined relative to a containing element.

Equality treats NaN scalars as equal to each other.

Fields

scalar: f64

The scalar.

unit: RelativeUnit

The unit of the scalar.

Implementations

impl RelativeScalar

pub const BEGINNING: RelativeScalar

The beginning of the containing element (0%).

pub const MIDDLE: RelativeScalar

The middle of the containing element (50%).

pub const END: RelativeScalar

The end of the containing element (100%).

pub const fn new(scalar: f64, unit: RelativeUnit) -> Self

pub fn equals(&self, other: RelativeScalar) -> bool

pub fn to_value(&self, size: f64) -> f64

Converts the scalar into a final value, using size as the size the scalar is relative to.

pub fn parse(s: &str) -> Result<Self, FormatError>

Parses a RelativeScalar string: "n" (absolute) or "n%" (relative).
