Commit-backend error that may occur after the backend is loaded.

Variants

InvalidHashLength

The caller attempted to read an object by specifying an ID with an invalid hash length for this backend.

Fields

expected: usize

The expected length of the hash in bytes for this backend.

actual: usize

The actual length of the hash in bytes that was provided.

object_type: String

The type of the object that we attempted to read, e.g. “commit” or “tree”.

hash: String

The hex hash that had an invalid length.

InvalidUtf8

The caller attempted to read an object that internally stored as invalid UTF-8, such as a symlink target with invalid UTF-8 stored in the Git backend.

Fields

object_type: String

The type of the object that we attempted to read, e.g. “commit” or “tree”.

hash: String

The hex hash of the object that had invalid UTF-8.

source: Utf8Error

The source error.

ObjectNotFound

The caller attempted to read an object that doesn’t exist.

Fields

object_type: String

The type of the object that we attempted to read, e.g. “commit” or “tree”.

hash: String

The hex hash of the object that was not found.

source: Box<dyn Error + Send + Sync>

The source error.

ReadObject

Failed to read an object due to an I/O error or other unexpected error.

Fields

object_type: String

The type of the object that we attempted to read, e.g. “commit” or “tree”.

hash: String

The hex hash of the object that we failed to read.

source: Box<dyn Error + Send + Sync>

The source error.

ReadAccessDenied

The caller attempted to read an object but doesn’t have permission to read it.

Fields

object_type: String

The type of the object that we attempted to read, e.g. “commit” or “tree”.

hash: String

The hex hash of the object that the caller doesn’t have permission to read.

source: Box<dyn Error + Send + Sync>

The source error.

ReadFile

Failed to read a file’s content due to an I/O error or other unexpected error.

Fields

path: RepoPathBuf

The path of the file we failed to read.

id: FileId

The ID of the file we failed to read.

source: Box<dyn Error + Send + Sync>

The source error.

WriteObject

Failed to write an object due to an I/O error or other unexpected error.

Fields

object_type: &'static str

The type of the object that we attempted to write, e.g. “commit” or “tree”.

source: Box<dyn Error + Send + Sync>

The source error.

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

Some other error that doesn’t fit into the above categories.

Unsupported(String)

A valid operation was attempted, but it failed because it isn’t supported by the particular backend.

Trait Implementations

impl Debug for BackendError

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

Formats the value using the given formatter.

impl Display for BackendError

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

Formats the value using the given formatter.

impl Error for BackendError

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.
