A Cargo workspace discovery, planning, or edit failure.

Variants

Read

A workspace file cannot be read.

Fields

path: PathBuf

The file.

source: Error

Why reading failed.

Manifest

A manifest is not valid TOML.

Fields

path: PathBuf

The manifest.

source: TomlError

The parse failure.

NoMembers

cargo metadata lists no workspace members.

MetadataSpawn(Error)

cargo metadata could not be started.

MetadataFailed

cargo metadata failed.

Fields

status: ExitStatus

The exit status.

stderr: String

The trimmed standard error output.

MetadataDecode(Box<DeserializeError>)

cargo metadata printed output that does not decode.

Duplicate(String)

Two workspace members share a package name.

UnknownUnit(String)

A proposal names a package outside the workspace.

NoManifestDirectory(PathBuf)

A member manifest path has no parent directory.

ManifestNotLoaded(PathBuf)

A member manifest was not parsed along with the workspace.

NoPackageTable(String)

A member manifest has no [package] table.

MissingVersionSource(String)

A member’s version is neither literal nor inherited from the workspace.

InvalidVersion

A version is not strict semver.

Fields

version: String

The rejected text.

source: Error

The parse failure.

IncompleteVersionGroup

A proposal covers only part of a shared version group.

Fields

version_source: VersionSource

Where the group’s version is set.

missing: Vec<String>

Members the proposal leaves out.

ConflictingVersionGroup

A shared version group received different targets.

Fields

version_source: VersionSource

Where the group’s version is set.

members: Vec<String>

The members with conflicting targets.

UnselectedDependencyConsumers

A shared dependency entry would change for packages outside the proposal.

Fields

dependency: String

The proposed package.

missing: Vec<String>

Consumers of the shared entry that are not proposed.

InvalidRequirement

A dependency requirement is not a valid semver requirement.

Fields

consumer: String

The package holding the requirement.

dependency: String

The required package.

requirement: String

The requirement as written.

source: Error

The parse failure.

UnsupportedDependencyRequirement

A requirement is too complex to rewrite safely.

Fields

consumer: String

The package holding the requirement.

dependency: String

The proposed package.

requirement: String

The requirement as written.

version: String

The proposed version.

MissingDependencySource

No manifest entry matches a dependency that cargo metadata reports.

Fields

consumer: String

The package holding the dependency.

dependency: String

The dependency.

Stale

A file changed between planning and applying.

Fields

path: PathBuf

The changed file.

Trait Implementations

impl Debug for WorkspaceError

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

Formats the value using the given formatter.

impl Display for WorkspaceError

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

Formats the value using the given formatter.

impl Error for WorkspaceError

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<WorkspaceError> for CargoError

fn from(source: WorkspaceError) -> Self

Converts to this type from the input type.
