Enum Projection

pub enum Projection {
    Perspective(PerspectiveProjection),
    Orthographic(OrthographicProjection),
}

A method of projection. Different projection types suitable for different purposes:

1. Perspective projection most useful for 3D games, it makes a scene to look most natural, objects will look smaller with increasing distance.
2. Orthographic projection most useful for 2D games, objects won’t look smaller with increasing distance.

Variants

Perspective(PerspectiveProjection)

See PerspectiveProjection docs.

Orthographic(OrthographicProjection)

See OrthographicProjection docs.

Trait Implementations

impl AsRef<str> for Projection

fn as_ref(&self) -> &str

Converts this type into a shared reference of the (usually inferred) input type.

impl Clone for Projection

fn clone(&self) -> Projection

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Projection

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

Formats the value using the given formatter.

impl Default for Projection

fn default() -> Self

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for Projection

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl FromStr for Projection

type Err = ParseError

The associated error which can be returned from parsing.

fn from_str(s: &str) -> Result<Projection, <Self as FromStr>::Err>

Parses a string s to return a value of this type.

impl PartialEq for Projection

fn eq(&self, other: &Projection) -> 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 Reflect for Projection

where Self: 'static, PerspectiveProjection: Reflect, OrthographicProjection: Reflect,

fn source_path() -> &'static str

fn type_name(&self) -> &'static str

fn doc(&self) -> &'static str

fn assembly_name(&self) -> &'static str

Returns a parent assembly name of the type that implements this trait. WARNING: You should use proc-macro (#[derive(Reflect)]) to ensure that this method will return correct assembly name. In other words - there’s no guarantee, that any implementation other than proc-macro will return a correct name of the assembly. Alternatively, you can use env!("CARGO_PKG_NAME") as an implementation.

fn type_assembly_name() -> &'static str

Returns a parent assembly name of the type that implements this trait. WARNING: You should use proc-macro (#[derive(Reflect)]) to ensure that this method will return correct assembly name. In other words - there’s no guarantee, that any implementation other than proc-macro will return a correct name of the assembly. Alternatively, you can use env!("CARGO_PKG_NAME") as an implementation.
