Enum ViewportOrigin 

pub enum ViewportOrigin {
    TopLeft,
    BottomLeft,
}

The origin convention for viewport coordinates.

Variants

TopLeft

Y-axis points downward (Direct3D / Vulkan surface convention).

BottomLeft

Y-axis points upward (OpenGL convention).

Implementations

impl ViewportOrigin

pub fn is_top_left(&self) -> bool

Returns true if this is the top-left (D3D/Vulkan) convention.

Trait Implementations

impl Clone for ViewportOrigin

fn clone(&self) -> ViewportOrigin

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for ViewportOrigin

impl Debug for ViewportOrigin

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

Formats the value using the given formatter.

impl Default for ViewportOrigin

fn default() -> ViewportOrigin

Returns the “default value” for a type.

impl Eq for ViewportOrigin

impl Hash for ViewportOrigin

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for ViewportOrigin

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