Variants

NotFound(String)

InvalidManifest(String)

NamespaceChanged(String)

Filesystem identity changed; never evidence of defective package contents.

RecoveryRetained

A package operation could not finish and kept the files it held at path: for example a claimed package it could not restore without replacing another occupant, or a staged package it could not publish. reason says why.

Fields

path: String

reason: String

ReplacementInterrupted

An update claimed the installed package and could neither publish its replacement nor put the claimed generation back. preserved holds that generation, in a transaction whose lease is released on return, so PluginHost::recover_interrupted_update can put it back, unless a package of that name is installed by then.

Fields

name: String

preserved: PathBuf

cause: String

MoveUnsupported(String)

The platform or filesystem has no rename that refuses an existing destination, so install removed the copy it staged and installed nothing; a retry there fails the same way.

MoveUnsupportedCleanup

The same permanent publication refusal, but cleanup did not complete. path names the failed cleanup operation, not a guarantee that all original payload bytes remain. This is never a recommendation to retry.

Fields

path: String

reason: String

InvalidConfig(String)

InvalidInstanceId(String)

InvalidEndpoint(String)

LoadFailed(String)

ExecutionFailed(String)

PermissionDenied

Fields

plugin: String

permission: String

AlreadyLoaded(String)

UnadmittedPackage

Something occupies a package name in the plugins directory that the host has not admitted as that package, and it was left as found. Install never overwrites it. remove deletes an unloaded directory only when it is empty, or when admission rejects its own contents rather than its signature. reason says why it was kept.

Fields

name: String

reason: String

UnsupportedCapability(String)

UnsignedPlugin(String)

UntrustedPublisher

Fields

plugin: String

publisher_key: String

SignatureInvalid(String)

PayloadDigestRequired(String)

PayloadDigestInvalid(String)

PayloadDigestMismatch

Fields

expected: String

actual: String

Io(Error)

TomlParse(Error)

Trait Implementations

impl Debug for PluginError

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

Formats the value using the given formatter.

impl Display for PluginError

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

Formats the value using the given formatter.

impl Error for PluginError

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<Error> for PluginError

fn from(source: Error) -> Self

Converts to this type from the input type.

impl From<Error> for PluginError

fn from(source: Error) -> Self
