Errors returned while reading a corpus.

Variants

Io(Error)

An I/O error occurred.

BadHeader

The header line did not match <prefix>IRTG (un)annotated corpus file, v1.0.

BadVersion

The header declared an unsupported corpus version.

MalformedInstance

An instance did not have the expected number of lines.

Fields

line: usize

1-based line number where the instance starts.

expected: usize

Number of lines expected for an instance.

found: usize

Number of non-blank lines found.

ObjectParse

An interpretation line could not be parsed by its algebra.

Fields

line: usize

1-based line number.

interpretation: String

Interpretation name.

message: String

Underlying parse error.

TreeParse

A derivation-tree line could not be parsed.

Fields

line: usize

1-based line number.

message: String

Underlying parse error.

Trait Implementations

impl Debug for CorpusError

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

Formats the value using the given formatter.

impl Display for CorpusError

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

Formats the value using the given formatter.

impl Error for CorpusError

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 CorpusError

fn from(source: Error) -> Self

Converts to this type from the input type.
