Enum TupleError4 

pub enum TupleError4<E0, E1, E2, E3> {
    At0(E0),
    At1(E1),
    At2(E2),
    At3(E3),
}

Transaction precondition error type for tuples of length 4.

Variants

At0(E0)

Error at tuple element 0.

At1(E1)

Error at tuple element 1.

At2(E2)

Error at tuple element 2.

At3(E3)

Error at tuple element 3.

Trait Implementations

impl<E0: Clone, E1: Clone, E2: Clone, E3: Clone> Clone for TupleError4<E0, E1, E2, E3>

fn clone(&self) -> TupleError4<E0, E1, E2, E3>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<E0: Debug, E1: Debug, E2: Debug, E3: Debug> Debug for TupleError4<E0, E1, E2, E3>

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

Formats the value using the given formatter.

impl<E0: Display, E1: Display, E2: Display, E3: Display> Display for TupleError4<E0, E1, E2, E3>

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

Formats the value using the given formatter.

impl<E0: Error, E1: Error, E2: Error, E3: Error> Error for TupleError4<E0, E1, E2, E3>

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<E0: PartialEq, E1: PartialEq, E2: PartialEq, E3: PartialEq> PartialEq for TupleError4<E0, E1, E2, E3>

fn eq(&self, other: &TupleError4<E0, E1, E2, E3>) -> 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.
