Failure returned by either snapshot operation.

Variants

ForeignPackage

The package identity was issued by a project rooted somewhere else.

StalePackage

The package identity was issued for another revision of this repository.

UnknownPackage

The package identity names a local index this project never issued.

Fields

index: u32

The absent local index.

ForeignTarget

The identity was issued by a project rooted somewhere else.

StaleTarget

The identity was issued for another revision of this repository.

UnknownTarget

The identity names a local index this project never issued.

Fields

index: u32

The absent local index.

ProjectManifestsChanged

A participating manifest changed after the project was loaded.

Fields

manifest: Box<str>

The repository-relative manifest that no longer matches.

ManifestUnreadable

A participating manifest could not be read while its revision was re-checked, so whether it still matches is unknown rather than false.

Fields

manifest: Box<str>

The repository-relative manifest that could not be read.

source: Error

The underlying I/O failure.

SourceClosure(SourceClosureError)

The target’s source closure could not be completed.

Trait Implementations

impl Debug for RustSnapshotError

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

Formats the value using the given formatter.

impl Display for RustSnapshotError

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

Formats the value using the given formatter.

impl Error for RustSnapshotError

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<SourceClosureError> for RustSnapshotError

fn from(source: SourceClosureError) -> Self

Converts to this type from the input type.
