Enum CompositeMode 

pub enum CompositeMode {
    Replace,
    SrcOver,
}

The composition mode that should be used when rendering into a pixmap.

For performance reason it is highly recommended that you use CompositeMode::Replace, even if you know that the pixmap is already cleared. Only use SrcOver if you really have to preserve existing contents.

Variants

Replace

Clear the destination pixmap and render the scene into it.

SrcOver

Render the scene into the pixmap using src-over compositing.

Trait Implementations

impl Clone for CompositeMode

fn clone(&self) -> CompositeMode

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for CompositeMode

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

Formats the value using the given formatter.

impl Default for CompositeMode

fn default() -> CompositeMode

Returns the “default value” for a type.

impl PartialEq for CompositeMode

fn eq(&self, other: &CompositeMode) -> 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 Copy for CompositeMode

impl Eq for CompositeMode

impl StructuralPartialEq for CompositeMode
