Variants

DeviceNotFound

Error encountered while connecting to a display-coordinator device via devfs.

NoDisplays

No displays were reported by the display driver when expected.

AlreadyRequested

A request handling task (such as one that owns a FIDL event stream that can only be started once) was already been initiated before.

BuffersNotAllocated

Error while allocating shared sysmem buffers.

SysmemConnection

Error while establishing a connection to sysmem.

IdsExhausted

Ran out of free client-assigned identifiers.

DevicePathInvalid

Path to the device is invalid (e.g. containing invalid characters).

FidlError(Error)

Wrapper for errors from FIDL bindings.

IoError(Error)

Wrapper for system file I/O errors.

ZxError(Status)

Wrapper for errors from zircon syscalls.

DeviceConnectionError(Error)

Wrapper for errors from FIDL device connections.

FsError(OpenError)

Wrapper for errors from fuchsia-fs.

WatcherCreateError(WatcherCreateError)

Wrapper for errors from fuchsia-fs watcher creation.

WatcherStreamError(WatcherStreamError)

Wrapper for errors from the fuchsia-fs watcher stream.

CouldNotSendVsyncEvent(TrySendError<VsyncEvent>)

Error that occurred while notifying vsync event listeners over an in-process async channel.

InvalidUtf8(Utf8Error)

UTF-8 validation error.

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)>

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
