Errors returned by core operations.

Variants

InvalidInput(String)

An argument does not satisfy the documented preconditions.

DataCompression

A compressed data bundle could not be decompressed.

Fields

name: String

Name of the bundle as declared in its manifest.

reason: String

Message from the decompressor.

DataChecksum

A data bundle failed its SHA-256 checksum.

Fields

name: String

Name of the bundle as declared in its manifest.

DataDigest

A data bundle declared a digest that is not 64 hexadecimal characters.

Fields

name: String

Name of the bundle as declared in its manifest.

DataJson

JSON decoding of a data bundle failed.

Fields

name: String

Name of the bundle as declared in its manifest.

reason: String

Message from the JSON decoder.

LimitExceeded(Verdict)

A size limit would be exceeded; the verdict explains what would fit.

Symmetry(String)

A symmetry search or space-group lookup failed.

Implementations

impl Error

pub fn code(&self) -> &'static str

Stable snake_case code for this error, suitable for bindings and JSON.

The string is part of the public API (see AGENTS.md, section 5.2).

pub fn message(&self) -> String

Human-readable message for this error.

pub fn category(&self) -> &'static str

Stable machine-readable category for the JSON error object.

Categories are input, unsupported, numerical, limit, engine and internal.

Trait Implementations

impl Clone for Error

fn clone(&self) -> Self

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

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 Eq for Error

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 PartialEq for Error

fn eq(&self, other: &Self) -> bool

Equality operator ==.

fn ne(&self, other: &Rhs) -> bool

Inequality operator !=.
