Errors thrown by the DrmDevice and the DrmSurface.

Variants

DrmMasterFailed

Unable to acquire DRM master

Access

The DrmDevice encountered an access error

Fields of Access

errmsg: &'static str

Error message associated to the access error

dev: Option<PathBuf>

Device on which the error was generated

source: SystemError

Underlying device error

UnableToGetDeviceId(Error)

Unable to determine device id of drm device

DeviceInactive

Device is currently paused

ModeNotSuitable(Mode)

Mode is not compatible with all given connectors

CrtcAlreadyInUse(Handle)

The given crtc is already in use by another surface

SurfaceWithoutConnectors(Handle)

This operation would result in a surface without connectors.

PlaneNotCompatible(Handle, Handle)

The given plane cannot be used with the given crtc

NonPrimaryPlane(Handle)

The given plane is not a primary plane and therefor not supported by the underlying implementation

NoSuitableEncoder

No encoder was found for a given connector on the set crtc

Fields of NoSuitableEncoder

connector: Handle

Connector

crtc: Handle

CRTC

UnknownProperty

The DrmDevice is missing a required property

Fields of UnknownProperty

handle: RawResourceHandle

Property handle

name: &'static str

Property name

TestFailed(Handle)

Atomic Test failed for new properties

Trait Implementations

impl Debug for Error

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

Formats the value using the given formatter.

impl Display for Error

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

Formats the value using the given formatter.

impl Error for Error

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

The lower-level source of this error, if any.

fn backtrace(&self) -> Option<&Backtrace>

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

Returns a stack backtrace, if available, of where this error occurred.

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

impl From<Error> for SwapBuffersError

fn from(err: Error) -> SwapBuffersError

Performs the conversion.

impl From<Error> for Error

fn from(source: DrmError) -> Self

Performs the conversion.
