The typed cause of a terminal OpenDAL Package Read failure.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

ResolveOperator(Box<dyn Error + Send + Sync>)

The reached binding could not be resolved.

UnsupportedTreeCapabilities

A reached tree binding cannot recursively list or read selected files.

Fields

list: bool

list_with_recursive: bool

read: bool

UnsupportedArchiveRead

A reached raw archive binding cannot read objects.

TreeList(Error)

A Package Tree recursive listing failed.

TreeRead(Error)

A listed Package Tree object read failed.

ListedTreeObjectAbsent(Error)

A listed Package Tree object became absent when read.

CacheRead(Error)

The raw Package Archive cache read failed.

RegistryRead(Error)

The official Package Registry read failed.

TreeStructural(PackageTreeReadSurveyError)

A completed Package Tree listing had envelope issues.

InvalidPackageTree(PackageTreeError)

Listed paths do not form a valid Package Tree.

TreeLimit(PackageTreeReadLimitError)

Package Tree Read exceeded a mandatory limit.

ArchiveLimit(PackageArchiveReadLimitError)

Raw Package Archive Read exceeded a mandatory limit.

Trait Implementations

impl Debug for PackageReadErrorCause

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

Formats the value using the given formatter.

impl Display for PackageReadErrorCause

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

Formats the value using the given formatter.

impl Error for PackageReadErrorCause

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.
