Struct BeginFrameReturns 

pub struct BeginFrameReturns {
    pub hasDamage: bool,
    pub screenshotData: Option<String>,
}

Sends a BeginFrame to the target and returns when the frame was completed. Optionally captures a screenshot from the resulting frame. Requires that the target was created with enabled BeginFrameControl. Designed for use with –run-all-compositor-stages-before-draw, see also https://goo.gle/chrome-headless-rendering for more background.

Fields

hasDamage: bool

Whether the BeginFrame resulted in damage and, thus, a new frame was committed to the display. Reported for diagnostic uses, may be removed in the future.

screenshotData: Option<String>

Base64-encoded image data of the screenshot, if one was requested and successfully taken. (Encoded as a base64 string when passed over JSON)
