Enum CompositingStrategy 

pub enum CompositingStrategy {
    Auto,
    Offscreen,
    ModulateAlpha,
}

Controls how a graphics layer is composited into its parent target.

Variants

Auto

Use renderer heuristics (default).

Offscreen

Render this layer to an offscreen target, then composite.

ModulateAlpha

Multiply alpha on source colors without allocating an offscreen layer.

Trait Implementations

impl Clone for CompositingStrategy

fn clone(&self) -> CompositingStrategy

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for CompositingStrategy

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

Formats the value using the given formatter.

impl Default for CompositingStrategy

fn default() -> CompositingStrategy

Returns the “default value” for a type.

impl Hash for CompositingStrategy

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

where __H: Hasher,

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 CompositingStrategy

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