Why no file of a call was made device-only (E8). Whatever the call made is removed before it returns, or, if removing it failed too, at the next open.

Variants

RepeatedFile

The call names one file twice.

Fields

file: FileId

The file.

Path(CopyPathError)

A copy can’t go where the app named it.

Database(DbError)

This device may not make a file device-only, or the write switching them failed: no record of the file here (FileAbsent), as for a file of a circle this member was never in; one not in the cloud (NotInCloud); an app file (NamespaceKind); a file of a circle this member has left (NotInCircle); or another member’s row of an owner_only table referencing it (NotOwner).

Download

Downloading a file failed.

Fields

file: FileId

The file.

error: FileReadError

The read’s failure.

Disk(FileError)

Writing a folder or a copy failed.

Cancelled

The app cancelled the call before its files switched.

Cleanup

Removing what the call made failed too. What stays is recorded, and the next open removes it.

Fields

error: Box<DeviceOnlyError>

The call’s failure.

cleanup: DbError

The removal’s.

Bug(Bug)

The call’s work panicked: a bug, which the caller reports (E15).

Trait Implementations

impl CarriesBug for DeviceOnlyError

fn bug(&self) -> Option<&Bug>

The bug this error carries, itself or through the failure it keeps.

impl Debug for DeviceOnlyError

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

Formats the value using the given formatter.

impl Display for DeviceOnlyError

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

Formats the value using the given formatter.

impl Error for DeviceOnlyError

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.
