Enum RepaintBufferType 

pub enum RepaintBufferType {
    NewBuffer,
    ReusedBuffer,
    SwappedBuffers,
}

Available on crate feature renderer-software only.

This enum describes which parts of the buffer passed to the SoftwareRenderer may be re-used to speed up painting.

Variants

NewBuffer

The full window is always redrawn. No attempt at partial rendering will be made.

ReusedBuffer

Only redraw the parts that have changed since the previous call to render().

This variant assumes that the same buffer is passed on every call to render() and that it still contains the previously rendered frame.

SwappedBuffers

Redraw the part that have changed since the last two frames were drawn.

This is used when using double buffering and swapping of the buffers.

Trait Implementations

impl Clone for RepaintBufferType

fn clone(&self) -> RepaintBufferType

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for RepaintBufferType

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

Formats the value using the given formatter.

impl Default for RepaintBufferType

fn default() -> RepaintBufferType

Returns the “default value” for a type.

impl PartialEq for RepaintBufferType

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