Errors returned by this library.

Variants

PathStepOverflow(i32, i32)

Returned when requested path-step trimming exceeds the available path depth.

NoClosestDir(String)

Returned when no matching directory name can be found while walking upward.

NoMatchingID(String)

Returned when an ItemId name has no tracked entries in the index.

IdAlreadyExists(String)

Returned when creating or renaming to an ID that already exists at the target path.

IdenticalSourceDestination(PathBuf)

Returned when source and destination resolve to the same filesystem path.

ExportDestinationInsideDatabase(PathBuf)

Returned when an export destination points inside the managed database root.

ImportSourceInsideDatabase(PathBuf)

Returned when an import source path points inside the managed database root.

RootIdUnsupported

Returned when an operation does not allow ItemId::database_id() as input.

NotADirectory(PathBuf)

Returned when a path was expected to be a directory but is not.

NotAFile(PathBuf)

Returned when a path was expected to be a file but is not.

OsStringConversion

Returned when converting an OS string/path segment into UTF-8 text fails.

NoParent(String)

Returned when an item has no parent inside the tracked database tree.

Io(Error)

Returned when an underlying filesystem I/O operation fails.

SerdeJson(Error)

Returned when JSON serialization or deserialization fails.

Bincode(Error)

Returned when bincode serialization or deserialization fails.

PathBufConversion(StripPrefixError)

Returned when converting an absolute path into a database-relative path fails.

Trait Implementations

impl Debug for DatabaseError

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

Formats the value using the given formatter.

impl Display for DatabaseError

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

Formats the value using the given formatter.

impl Error for DatabaseError

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
