Struct Errors

pub struct Errors { /* private fields */ }

A type holding multiple errors that occurred during in-place expression evaluation via Evaluate::evaluate_in_place.

It is guaranteed that Errors instances hold at least one error.

Implementations

impl Errors

pub fn len(&self) -> usize

Returns the number of errors.

pub fn iter(&self) -> Iter<'_, Error>

Returns an iterator over all errors.

Trait Implementations

impl Clone for Errors

fn clone(&self) -> Errors

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Errors

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

Formats the value using the given formatter.

impl Display for Errors

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

Formats the value using the given formatter.

impl Error for Errors

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> for Errors

fn from(error: Error) -> Self

Converts to this type from the input type.

impl<'a> IntoIterator for &'a Errors

type Item = &'a Error

The type of the elements being iterated over.

type IntoIter = Iter<'a, Error>

Which kind of iterator are we turning this into?

fn into_iter(self) -> Self::IntoIter

Creates an iterator from a value.

impl IntoIterator for Errors

type Item = Error

The type of the elements being iterated over.

type IntoIter = IntoIter<Error>

Which kind of iterator are we turning this into?

fn into_iter(self) -> Self::IntoIter

Creates an iterator from a value.

impl PartialEq for Errors

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

Tests for self and other values to be equal, and is used by ==.

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

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
