Implementations

impl ScaledUnit

pub fn parse(s: &str) -> Option<Self>

Parses a unit from a two character abbreviation.

E.g., "pc" is parsed to ScaledUnit::Pica. These are abreviations are defined in TeX.2021.458 and chapter 10 of the TeX book.

pub fn conversion_fraction(&self) -> (i32, i32)

Returns the fraction needed to convert to/from this unit to points.

The return value is of the form (n, d). If a scaled number represents _x_in these units (e.g. y ScaledUnit::Pica), then it is y=nx/d points.

Defined in TeX.2021.458.

Trait Implementations

impl Clone for ScaledUnit

fn clone(&self) -> ScaledUnit

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for ScaledUnit

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

Formats the value using the given formatter.

impl PartialEq for ScaledUnit

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