Enum DxgiCaptureSourceError 

pub enum DxgiCaptureSourceError {
    Windows(Error),
    NoSuchOutput(u32),
    AccessLost,
    SeekUnsupported,
    RegionOutsideDesktop(CaptureRect),
    RegionSpansMultipleAdapters,
    CursorUnsupportedForRegion,
}

Available on Windows and crate feature dxgi-capture and (crate features dxgi-capture or wasapi-capture) only.

Errors specific to DxgiCaptureSource. Converts into the crate-wide Error via ? (see crate::error::Error).

Variants

Windows(Error)

NoSuchOutput(u32)

AccessLost

DXGI_ERROR_ACCESS_LOST specifically, broken out of the generic DxgiCaptureSourceError::Windows variant because it’s the single most common recoverable failure mode for desktop duplication — a lock screen, a UAC prompt, a display mode change, or a fullscreen-exclusive app/overlay stealing the duplication lock all surface this way. Same “fail fast, caller rebuilds a fresh one” contract crate::elements::RtspSource already documents: this element doesn’t retry internally, callers that want to survive a lock-screen cycle watch for this specific error and call DxgiCaptureSource::open again.

SeekUnsupported

RegionOutsideDesktop(CaptureRect)

RegionSpansMultipleAdapters

See CaptureArea::Region’s own docs on why this is a hard failure rather than an automatic CPU-bridged fallback.

CursorUnsupportedForRegion

Trait Implementations

impl Debug for DxgiCaptureSourceError

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

Formats the value using the given formatter.

impl Display for DxgiCaptureSourceError

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

Formats the value using the given formatter.

impl Error for DxgiCaptureSourceError

fn source(&self) -> Option<&(dyn Error + 'static)>

Returns the lower-level source of this error, if any.

fn description(&self) -> &str

👎Deprecated since 1.42.0:

use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting

fn provide<'a>(&'a self, request: &mut Request<'a>)

🔬This is a nightly-only experimental API. (error_generic_member_access)

Provides type-based access to context intended for error reports.
