Struct UnitScale 

pub struct UnitScale {
    pub length_to_metres: f64,
    pub angle_to_radians: f64,
}

Multipliers converting file units into SI base units.

Fields

length_to_metres: f64

Multiply a stored length by this to get metres.

angle_to_radians: f64

Multiply a stored plane angle by this to get radians.

Implementations

impl UnitScale

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

Convert a stored length to metres.

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

Convert a stored plane angle to radians.

pub fn is_metric_identity(&self) -> bool

Are lengths already in metres?

Trait Implementations

impl Clone for UnitScale

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for UnitScale

impl Debug for UnitScale

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

Formats the value using the given formatter.

impl Default for UnitScale

fn default() -> Self

SI defaults: metres and radians, both factor 1.

Used only when a file declares no units at all. That is malformed, but refusing to load such a file is worse than assuming SI and saying so.

impl PartialEq for UnitScale

fn eq(&self, other: &Self) -> bool

Equality operator ==.

fn ne(&self, other: &Rhs) -> bool

Inequality operator !=.
