pub struct ErrorBase<E = Box<dyn Error + 'static>> { /* private fields */ }

Implementations

impl<E> ErrorBase<E>

where E: Error,

pub const fn new(kind: ErrorKind, source: Option<E>) -> Self

pub const fn unknown(source: E) -> Self

pub fn with_kind(self, kind: ErrorKind) -> ErrorBase<E>

consumes the current error to create another of the given kind

pub fn with_source<E2>(self, source: E2) -> ErrorBase<E2>

where E2: Error,

consumes the current error to create another with the given message

Trait Implementations

impl<E: Clone> Clone for ErrorBase<E>

fn clone(&self) -> ErrorBase<E>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<E: Debug> Debug for ErrorBase<E>

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

Formats the value using the given formatter.

impl<E> Display for ErrorBase<E>

where E: 'static + Error,

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

Formats the value using the given formatter.

impl<E> Error for ErrorBase<E>

where E: 'static + Error,

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<T> From<Option<T>> for ErrorBase

where T: Error + 'static,

fn from(opt: Option<T>) -> Self

Converts to this type from the input type.

impl From<Utf8Error> for ErrorBase

fn from(err: Utf8Error) -> Self

Converts to this type from the input type.

impl<E: Hash> Hash for ErrorBase<E>

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<E: Ord> Ord for ErrorBase<E>

fn cmp(&self, other: &ErrorBase<E>) -> 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<E: PartialEq> PartialEq for ErrorBase<E>

fn eq(&self, other: &ErrorBase<E>) -> 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<E: PartialOrd> PartialOrd for ErrorBase<E>

fn partial_cmp(&self, other: &ErrorBase<E>) -> 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.
