Available on Windows only.

Metadata about a captured frame.

This structure contains timing information, dirty regions, moved regions, and other metadata that can help optimize screen capture and streaming applications.

Fields

last_present_time: i64

Timestamp of the last desktop image update (Windows performance counter)

last_mouse_update_time: i64

Timestamp of the last mouse update (Windows performance counter)

accumulated_frames: u32

Number of frames accumulated since the last processed frame

rects_coalesced: bool

Whether dirty regions were coalesced and may contain unmodified pixels

protected_content_masked_out: bool

Whether protected content was masked out in the captured frame

pointer_position: Option<(i32, i32)>

Mouse cursor position and visibility

pointer_visible: bool

Whether the mouse cursor is visible

dirty_rects: Vec<(i32, i32, i32, i32)>

List of dirty rectangles that have changed since the last frame

move_rects: Vec<MoveRect>

List of move rectangles that have been moved since the last frame

Implementations

impl FrameMetadata

pub fn has_updates(&self) -> bool

Returns true if the frame contains any updates (dirty regions or moves)

pub fn has_mouse_updates(&self) -> bool

Returns true if the mouse cursor has been updated

pub fn total_change_count(&self) -> usize

Returns the total number of changed regions

Trait Implementations

fn clone(&self) -> FrameMetadata

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for FrameMetadata

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

Formats the value using the given formatter.
