Implementations

impl<E> Cause<E>

pub fn message(self, value: E) -> Self

Sets the message field of this struct.

pub fn description(self, value: E) -> Self

Sets the description field of this struct.

impl<E> Cause<E>

pub fn new(e: E) -> Self

pub fn transform<E1>(self, e: impl Fn(E) -> E1) -> Cause<E1>

pub fn trace<T: Display>(self, trace: Vec<T>) -> Self

Trait Implementations

impl<E: Clone> Clone for Cause<E>

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

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<E: Debug> Debug for Cause<E>

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

Formats the value using the given formatter.

impl<E: Display> Display for Cause<E>

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

Formats the value using the given formatter.

impl<E> Error for Cause<E>

where Self: Debug + Display,

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<E> From<Cause<E>> for ValidationError<E>

fn from(value: Cause<E>) -> Self

Converts to this type from the input type.

impl<E: PartialEq> PartialEq for Cause<E>

fn eq(&self, other: &Cause<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.
