Struct re_renderer::Size

#[repr(C)]
pub struct Size(pub f32);

A size of something in either world-units, screen-units, or unsized.

Implementation:

• If positive, this is in scene units.
• If negative, this is in points.
• If NaN, auto-size it.

Resolved on-the-fly in shader code. See shader/utils/size.wgsl

Implementations

impl Size

pub const AUTO: Self = _

Automatically sized, based on a view builder setting.

pub const AUTO_LARGE: Self = _

Like Size::AUTO, but larger by some small factor (~2).

pub fn new_scene(size: f32) -> Self

Creates a new size in scene units.

Values passed must be finite positive.

pub fn new_points(size: f32) -> Self

Creates a new size in ui point units.

Values passed must be finite positive.

pub fn is_auto(&self) -> bool

Returns true if the size is an automatically determined size (Self::AUTO or Self::AUTO_LARGE).

pub fn scene(&self) -> Option<f32>

Get the scene-size of this, if stored as a scene size.

pub fn points(&self) -> Option<f32>

Get the point size of this, if stored as a point size.

Trait Implementations

impl Clone for Size

fn clone(&self) -> Size

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Size

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Size

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Mul<f32> for Size

type Output = Size

The resulting type after applying the * operator.

fn mul(self, rhs: f32) -> Self::Output

Performs the * operation.

impl MulAssign<f32> for Size

fn mul_assign(&mut self, rhs: f32)

Performs the *= operation.

impl PartialEq for Size

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

This method tests for self and other values to be equal, and is used by ==.

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

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serialize for Size

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

Serialize this value into the given Serde serializer.

impl Zeroable for Size

fn zeroed() -> Self

Calls zeroed.

impl Copy for Size

impl Pod for Size
