Enum ParseGroError

pub enum ParseGroError {
    IOError(Error),
    UnexpectedEOF(ExpectedItem),
    UnexpectedEOL(ExpectedItem),
    BadNAtoms(ParseIntError),
    InsufficientAtoms {

}

The error type for reading gro files.

A distinction is made between I/O, unexpected end-of, and bad-value errors.

A ParseGroError can always be cast to an io::Error. If the error is of the ParseGroError::IOError variant, the inner io::Error will be used directly. Otherwise, the error is converted to an instance of io::ErrorKind::Other.

Similarly, any io::Error can be cast to a ParseGroError. This makes conversion between error types convenient and allows for using the try-operator (?) in both reader::Result and io::Result-returning function.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Trait Implementations

impl Debug for ParseGroError

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

Formats the value using the given formatter.

impl Display for ParseGroError

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

Formats the value using the given formatter.

impl Error for ParseGroError

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.
