Implementations

impl Error

pub fn span(&self) -> &Option<Span>

&self.span_maybe

pub fn level(&self) -> Level

self.level

pub fn new(span_maybe: Option<Span>, level: Level, description: &str) -> Self

A constructor for Error.

pub fn description(&self) -> &str

&self.description.

Trait Implementations

impl AddAssign<Error> for &mut Error

fn add_assign(&mut self, error: Error)

Performs the += operation.

impl AddAssign<Rc<Error>> for &mut Error

fn add_assign(&mut self, error: Rc<Error>)

Performs the += operation.

impl AddAssign<Rc<Error>> for Error

fn add_assign(&mut self, error: Rc<Error>)

Performs the += operation.

impl AddAssign for Error

fn add_assign(&mut self, error: Error)

Performs the += operation.

impl Clone for Error

fn clone(&self) -> Error

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Error

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

Formats the value using the given formatter.

impl Default for Error

fn default() -> Self

Returns the “default value” for a type.

impl Display for Error

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

Formats the value using the given formatter.

impl Hash for Error

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl IntoIterator for Error

type Item = Rc<Error>

The type of the elements being iterated over.

type IntoIter = IntoIter<<Error as IntoIterator>::Item>

Which kind of iterator are we turning this into?

fn into_iter(self) -> Self::IntoIter

Creates an iterator from a value.

impl Ord for Error

fn cmp(&self, other: &Self) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for Error

fn eq(&self, other: &Error) -> 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.

impl PartialOrd for Error

fn partial_cmp(&self, other: &Self) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.

impl RangeBounds<usize> for Error

fn start_bound(&self) -> Bound<&usize>

Start index bound.

fn end_bound(&self) -> Bound<&usize>

End index bound.

fn contains<U>(&self, item: &U) -> bool

where T: PartialOrd<U>, U: PartialOrd<T> + ?Sized,

Returns true if item is contained in the range.

fn is_empty(&self) -> bool

where T: PartialOrd,

🔬This is a nightly-only experimental API. (range_bounds_is_empty)

Returns true if the range contains no items. One-sided ranges (RangeFrom, etc) always return false.
