Enum GraphFromFileError

pub enum GraphFromFileError<'a> {
    FileError(IOError),
    PestParseError(PestError),
    ParseError(ParseError<'a>),
}

An error that can occur when reading from a file.

Variants

FileError(IOError)

The error occured when manipulating the file (e.g. the file does not exist).

PestParseError(PestError)

The error occured when parsing the file (e.g. the pest parser returned an error).

ParseError(ParseError<'a>)

The error occured when traversing the Rules tree returned by the pest parser. Such error occuring is likely a bug or a missing feature of the library.

Trait Implementations

impl<'a> Debug for GraphFromFileError<'a>

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

Formats the value using the given formatter.

impl Display for GraphFromFileError<'_>

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

Formats the value using the given formatter.

impl Error for GraphFromFileError<'_>

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<Rule>> for GraphFromFileError<'_>
