Errors returned by this library.

Conversion failures are not errors. They are recorded outcomes in the manifest. This type covers the cases where the pipeline itself cannot proceed.

Variants

Io

A filesystem operation failed.

Fields

op: &'static str

The operation that failed, such as open or read.

path: PathBuf

The path the operation touched.

source: Error

The underlying error.

Rules

A rules file failed to parse or validate.

Fields

name: String

The rules file name.

message: String

What went wrong.

Manifest

A manifest shard failed to parse or validate.

Fields

path: PathBuf

The shard path.

line: usize

The one-based line number.

message: String

What went wrong.

Encode

A manifest record could not be encoded.

Fields

path: PathBuf

The shard path.

message: String

What went wrong.

Division

A division name is not usable as a shard file name.

Fields

name: String

The rejected name.

Layout

The run layout is invalid.

Fields

message: String

What is wrong with the layout.

Refused

A bundle verb examined its input and refused it, naming every offender. Refusal is an outcome, distinct from a verb that could not run.

Fields

verb: &'static str

The verb that refused.

problems: Vec<String>

Every offending file, record, or field.

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.
