The webrtc feature pulls time 0.3 into scrap's graph (hbb_common ->
webrtc -> webrtc-dtls -> der-parser -> asn1-rs), and that crate carries
an `impl Div<time::Duration> for std::time::Duration`. Orphan rules
allow it because the RHS is its own type, and trait impls are visible
across the whole dependency graph without a use, so std::time::Duration
now has two Div candidates. `yuv_count as _` casts to a plain inference
variable, which both candidates fit, so it stops resolving:
error[E0282]: type annotations needed
--> libs/scrap/examples/benchmark.rs:146:33
Only two of the four sites are reported - rustc emits one E0282 per
function body - so all four are annotated. The already-explicit
`as u32` at the hwcodec site and `start.elapsed() / cnt` are unaffected,
the latter because an integer literal's variable can only unify with an
integral type and rules the time impl out on its own.

scrap
Scrap records your screen! At least it does if you're on Windows, macOS, or Linux.
Usage
[dependencies]
scrap = "0.5"
Its API is as simple as it gets!
struct Display; /// A screen.
struct Frame; /// An array of the pixels that were on-screen.
struct Capturer; /// A recording instance.
impl Capturer {
/// Begin recording.
pub fn new(display: Display) -> io::Result<Capturer>;
/// Try to get a frame.
/// Returns WouldBlock if it's not ready yet.
pub fn frame<'a>(&'a mut self) -> io::Result<Frame<'a>>;
pub fn width(&self) -> usize;
pub fn height(&self) -> usize;
}
impl Display {
/// The primary screen.
pub fn primary() -> io::Result<Display>;
/// All the screens.
pub fn all() -> io::Result<Vec<Display>>;
pub fn width(&self) -> usize;
pub fn height(&self) -> usize;
}
impl<'a> ops::Deref for Frame<'a> {
/// A frame is just an array of bytes.
type Target = [u8];
}
The Frame Format
- The frame format is guaranteed to be packed BGRA.
- The width and height are guaranteed to remain constant.
- The stride might be greater than the width, and it may also vary between frames.
