}

Native CIF syntax, limit, lookup, or domain failure.

A returned error means no scientifically valid structure was produced. Recoverable decisions on a successful permissive import are represented by CifDiagnostic instead.

Variants

InvalidLimits

One or more configured limits are zero.

ByteLimitExceeded

UTF-8 input exceeds the configured byte limit.

Fields

actual: u64

Observed byte count.

maximum: usize

Configured maximum.

Io(Error)

Filesystem or UTF-8 reading failed.

Syntax

CIF tokenization or document structure is invalid.

Fields

message: String

Stable explanation.

line: Option<usize>

One-based source line when known.

Limit

A parser or import resource limit was exceeded.

Fields

message: String

Stable explanation including the limit name.

Import

A syntactically valid CIF cannot form the requested structure.

Fields

message: String

Stable explanation.

Unsupported

A deliberately unsupported CIF feature was encountered in strict mode.

Fields

feature: String

Unsupported feature family.

message: String

Human-readable explanation.

SpaceGroup(SpaceGroupLookupError)

Native space-group lookup failed.

Cell(CellError)

Unit-cell validation failed.

Symmetry(SymmetryError)

Exact operation validation failed.

Trait Implementations

impl Debug for CifIoError

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

Formats the value using the given formatter.

impl Display for CifIoError

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

Formats the value using the given formatter.

impl Error for CifIoError

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.
