Enum DictError 

pub enum DictError {
    InvalidCharacter(char, Option<usize>, Option<usize>),
    MissingColumnInIndex(usize),
    InvalidFileFormat(String, Option<String>),
    MemoryError,
    WordNotFound(String),
    IoError(Error),
    Utf8Error(FromUtf8Error),
    DeflateError(DecompressError),
}

Error type, representing the errors which can be returned by the libdict library.

This enum represents a handful of custom errors and wraps io:::Error and string::FromUtf8Error.

Variants

InvalidCharacter(char, Option<usize>, Option<usize>)

Invalid character, e.g. within the index file; the error contains the erroneous character, and optionally line and position.

MissingColumnInIndex(usize)

Occurs whenever a line in an index file misses a column.

InvalidFileFormat(String, Option<String>)

Invalid file format, contains an explanation an optional path to the file with the invalid file format.

MemoryError

This reports a malicious / malformed index file, which requests a buffer which is too large.

WordNotFound(String)

This reports words which are not present in the dictionary.

IoError(Error)

A wrapped io::Error.

Utf8Error(FromUtf8Error)

A wrapped Utf8Error.

DeflateError(DecompressError)

Errors thrown by the flate2 crate - not really descriptive errors, though.

Trait Implementations

impl Debug for DictError

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

Formats the value using the given formatter.

impl Display for DictError

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

Formats the value using the given formatter.

impl Error for DictError

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<DecompressError> for DictError

fn from(err: DecompressError) -> DictError

Converts to this type from the input type.

impl From<Error> for DictError

fn from(err: Error) -> DictError

Converts to this type from the input type.

impl From<FromUtf8Error> for DictError

fn from(err: FromUtf8Error) -> DictError

Converts to this type from the input type.
