Stable one-volume generation transaction failures.

Variants

Plan(MutationPlanError)

A path mutation planner rejected the batch.

Config(VolumeConfigError)

Volume limits or semantic configuration are invalid.

TooManyPaths

Mutation endpoints exceed the admitted shared-path batch bound.

InvalidInitialLinkCount

A newly created record must begin with exactly one namespace binding.

UnsupportedSymbolicLink

The volume does not admit symbolic links.

UnsupportedFileKind

The volume profile cannot represent the created kind exactly.

UnsupportedSparseMutation

The requested operation can introduce sparse semantics in a dense volume.

Path(PathLookupError)

Shared authenticated path resolution failed.

FileRecord(FileRecordReadError)

Created-identity freshness lookup failed.

MissingParent

One operation requires a parent directory absent from the candidate view.

MissingSource

One operation requires an existing source binding.

AlreadyExists

A create/link/rename destination expected absence.

FileIdentityConflict

A supplied exact file identity precondition failed.

FileIdentityAlreadyExists

A create reused an identity already present in the base or batch.

UnsupportedHardLink

A hard link targeted a directory or a volume without hard-link support.

DirectoryCycle

A directory move would place the directory below itself.

DirectoryNotEmpty

A removed or replaced directory is not empty in the candidate view.

InconsistentState

Authenticated state and sparse planning disagree.

Tree(TreeMutationError)

Directory path-copy failed.

FileTable(FileTableMutationError)

File-table path-copy failed.

Regular(RegularMutationError)

Regular-file sparse mutation failed.

Directory(DirectoryReadError)

Bounded empty-directory proof failed.

AllocationFailed

Bounded scratch storage could not be allocated.

Work(WorkError)

Exact work overflowed or exceeded the request budget.

Trait Implementations

impl Debug for GenerationMutationError

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

Formats the value using the given formatter.

impl Display for GenerationMutationError

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

Formats the value using the given formatter.

impl Error for GenerationMutationError

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.
