Struct DatumError

pub struct DatumError {
    pub kind: DatumErrorKind,
    pub offset: DatumOffset,
    pub message: &'static str,
}

Datum error. Notably, writing uses a different error type, so these are read-focused.

Fields

kind: DatumErrorKind

Kind of error. Useful to distingulish EOF errors from non-EOF errors.

offset: DatumOffset

Error occurred at this offset. Offsets are entirely caller-supplied, except when iterator wrapping is in use.

message: &'static str

Message.

Trait Implementations

impl Clone for DatumError

fn clone(&self) -> DatumError

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

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

Formats the value using the given formatter.

impl Display for DatumError

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

impl Error for DatumError

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
