Struct Projection2 

pub struct Projection2 { /* private fields */ }

A tiny 2D projection descriptor.

Implementations

impl Projection2

pub const fn new(kind: ProjectionKind, scale: f64) -> Option<Projection2>

Creates a projection with a positive finite scale.

pub const fn kind(self) -> ProjectionKind

Returns the projection kind.

pub const fn scale(self) -> f64

Returns the projection scale.

pub fn project_x_axis(self, point: Point2) -> f64

Projects a point onto the x axis and applies the projection scale.

Trait Implementations

impl Clone for Projection2

fn clone(&self) -> Projection2

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Projection2

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

Formats the value using the given formatter.

impl PartialEq for Projection2

fn eq(&self, other: &Projection2) -> 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.
