Struct Cause

pub struct Cause<E, T> {
    pub error: E,
    pub trace: VecDeque<T>,
}

Fields

error: E

trace: VecDeque<T>

Implementations

impl<E, T> Cause<E, T>

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

Sets the error field of this struct.

impl<E, T> Cause<E, T>

pub fn new(e: E) -> Self

pub fn trace(self, t: T) -> Self

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

Trait Implementations

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

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

Returns a duplicate of the value.

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

Performs copy-assignment from source.

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

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

Formats the value using the given formatter.

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

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

Formats the value using the given formatter.

impl<E, T> Error for Cause<E, T>

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<A, E, T> From<Cause<E, T>> for Valid<A, E, T>

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

Converts to this type from the input type.

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

fn eq(&self, other: &Cause<E, T>) -> 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.
