Struct DataError 

pub struct DataError { /* private fields */ }

Why rows could not be read: what went wrong, and where when the source knows (a 1-based line or record number).

Implementations

impl DataError

pub fn new(message: impl Into<String>) -> Self

An error with no position.

pub fn at(line: usize, message: impl Into<String>) -> Self

An error at a 1-based line or record.

pub fn line(&self) -> Option<usize>

The 1-based line or record, when known.

pub fn message(&self) -> &str

The message, without the position.

Trait Implementations

impl Clone for DataError

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for DataError

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

Formats the value using the given formatter.

impl Display for DataError

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

Formats the value using the given formatter.

impl Eq for DataError

impl Error for DataError

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 PartialEq for DataError

fn eq(&self, other: &Self) -> bool

Equality operator ==.

fn ne(&self, other: &Rhs) -> bool

Inequality operator !=.
