Implementations

impl Viewport

pub fn new(center: Vec2, size: Vec2) -> Self

pub fn rect(&self) -> Rect

Axis-aligned view rectangle in Field space.

pub fn move_to(&mut self, center: Vec2)

Move camera to a new center.

Trait Implementations

impl Clone for Viewport

fn clone(&self) -> Viewport

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Viewport

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

Formats the value using the given formatter.

impl PartialEq for Viewport

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