Capability-scoped host filesystem observation failure.

Variants

Io

A user-visible workspace operation failed.

Fields

operation: &'static str

Stable operation label.

path: VPath

Exact virtual path.

source: Error

Underlying host error.

InternalIo

An internal runtime-directory operation failed.

Fields

operation: &'static str

Stable operation label.

path: PathBuf

Capability-relative internal path.

source: Error

Underlying host error.

UnsupportedNode

The host entry is neither a regular file, directory, nor symbolic link.

Fields

path: VPath

Rejected path.

NonUtf8Name

A host name cannot be represented by portable VPath UTF-8.

Fields

parent: VPath

Directory containing the name.

name: OsString

Rejected host name.

NonUtf8Symlink

A Windows symbolic-link target cannot be represented portably.

Fields

path: VPath

Rejected link path.

MissingFileIdentity

The platform did not expose a stable node identity.

Fields

path: VPath

Affected path.

Unstable

Metadata changed around a supposedly stable read or enumeration.

Fields

path: VPath

Affected path.

before: Box<FileStamp>

First metadata observation.

after: Box<FileStamp>

Second metadata observation.

SnapshotLimit

Snapshot traversal exceeded a configured bound.

Fields

limit: &'static str

Stable limit name.

observed: u64

Observed value.

maximum: u64

Configured maximum.

Snapshot(SnapshotError)

Immutable snapshot construction failed.

Trait Implementations

impl Debug for HostError

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

Formats the value using the given formatter.

impl Display for HostError

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

Formats the value using the given formatter.

impl Error for HostError

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.

impl From<HostError> for CommitError

fn from(source: HostError) -> Self

Converts to this type from the input type.
