Struct webrender::renderer::BufferDamageTracker

pub(crate) struct BufferDamageTracker {
    damage_rects: [DeviceRect; 4],
    current_offset: usize,
}

Tracks buffer damage rects over a series of frames.

Fields

current_offset: usize

Implementations

impl BufferDamageTracker

fn push_dirty_rect(&mut self, rect: &DeviceRect)

Sets the damage rect for the current frame. Should only be called after get_damage_rect() has been called to get the current backbuffer’s damage rect.

fn get_damage_rect(&self, buffer_age: usize) -> Option<DeviceRect>

Gets the damage rect for the current backbuffer, given the backbuffer’s age. (The number of frames since it was previously the backbuffer.) Returns an empty rect if the buffer is valid, and None if the entire buffer is invalid.
