Implementations

impl<E> ErrorBase<E>

where E: Error,

pub fn from_err(inner: E) -> Self

returns a new instance wrapping the given error.

pub fn into_inner(self) -> E

consumes the wrapper to return the inner value.

pub const fn get(&self) -> &E

returns an immutable reference to the underlying error.

pub fn get_mut(&mut self) -> &mut E

returns a mutable reference to the underlying error.

pub fn replace(&mut self, new: E) -> E

uses the replace method to replace and return the current error with another.

pub fn set(&mut self, new: E) -> &mut Self

update the inner value before returning a mutable reference to the wrapper;

pub fn swap(&mut self, other: &mut Self)

swap out the inner values of two instances of [RawError].

pub fn map<V, F>(self, f: F) -> ErrorBase<V>

where F: FnOnce(E) -> V, V: Error,

apply a function to the error and return a new instance with the result.

pub fn map_mut<F>(&mut self, f: F)

where F: FnOnce(&mut E),

mutate the error using the given function

Trait Implementations

impl<E> Clone for ErrorBase<E>

where E: Error + Clone,

Formats the value using the given formatter.

impl<E> Default for ErrorBase<E>

where E: Error + Default,

Returns the “default value” for a type.

impl<'de, E> Deserialize<'de> for ErrorBase<E>

impl<E: Error> Error for ErrorBase<E>

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<'a, E> From<&'a ErrorBase<E>> for ErrorBase<E>

where E: Error + Clone,

fn from(inner: &'a ErrorBase<E>) -> Self

Converts to this type from the input type.

impl<E> From<E> for ErrorBase<E>

where E: Error,

fn from(inner: E) -> Self

Converts to this type from the input type.

impl<E> Hash for ErrorBase<E>

where E: Error + Hash,

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 for ErrorBase<E>

where E: Error + Ord,

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.

impl<E> PartialEq for ErrorBase<E>

where E: Error + PartialEq,

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.
