Enum Error 

#[non_exhaustive]
pub enum Error {
    InputOutput(Error),
    InvalidFormat {
        details: String,
    },
    SegmentNotFound {
        segment_identifier: SegmentIdentifier,
    },
    ExternalBinaryContentUnavailable {
        blob_identifier: String,
    },
}

The error type for every fallible operation in this crate.

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.

InputOutput(Error)

An underlying input/output operation failed.

InvalidFormat

A file or byte sequence did not match the segment-tar storage format.

Fields

details: String

Human-readable description of what was expected and what was found.

SegmentNotFound

A record referenced a segment that no archive of the repository contains. This mirrors Oak’s SegmentNotFoundException and can be caused by garbage collection removing a segment while old record identifiers to it survive.

Fields

segment_identifier: SegmentIdentifier

The identifier of the missing segment.

ExternalBinaryContentUnavailable

The content of a binary stored in an external blob store was requested; the segment store only holds the binary’s identifier.

Fields

blob_identifier: String

The identifier of the binary in the external blob store.

Trait Implementations

impl Debug for Error

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

Formats the value using the given formatter.

impl Display for Error

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

Formats the value using the given formatter.

impl Error for Error

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 Error

fn from(source: Error) -> Self

Converts to this type from the input type.
