Struct Zoom 

pub struct Zoom(Bounded<ZoomBounds>);

A newtype rather than a Bounded<ZoomBounds> alias so Zoom::unity can be inherent; the clamping and the total order are Bounded’s.

Tuple Fields

0: Bounded<ZoomBounds>

Implementations

impl Zoom

pub const WORKED_MIN: Self

The band the user’s own zoom — the wheel, a pinch, a keyboard step — lands in. Deliberately narrower than the type’s own bounds, which the framing helpers are allowed to use in full.

pub const WORKED_MAX: Self

pub const fn new(scale: f32) -> Self

pub const fn get(self) -> f32

pub const fn unity() -> Self

pub const fn min_value() -> Self

pub const fn max_value() -> Self

pub fn framing(viewport: Vec2, content: Vec2, max_zoom: Self) -> Self

The zoom that fits a content-sized box within a viewport-sized one, capped at max_zoom. Padding is the caller’s: it pads content before framing it.

Trait Implementations

impl Clone for Zoom

fn clone(&self) -> Zoom

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Zoom

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Zoom

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl From<Zoom> for f32

fn from(zoom: Zoom) -> f32

Converts to this type from the input type.

impl Ord for Zoom

fn cmp(&self, other: &Zoom) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for Zoom

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

impl PartialOrd for Zoom

fn partial_cmp(&self, other: &Zoom) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.

impl Serialize for Zoom

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
