Enum TupleError2 

pub enum TupleError2<E0, E1> {
    At0(E0),
    At1(E1),
}

Transaction precondition error type for tuples of length 2.

Variants

At0(E0)

Error at tuple element 0.

At1(E1)

Error at tuple element 1.

Trait Implementations

impl<E0: Clone, E1: Clone> Clone for TupleError2<E0, E1>

fn clone(&self) -> TupleError2<E0, E1>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<E0: Debug, E1: Debug> Debug for TupleError2<E0, E1>

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

Formats the value using the given formatter.

impl<E0: Display, E1: Display> Display for TupleError2<E0, E1>

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

Formats the value using the given formatter.

impl<E0: Error, E1: Error> Error for TupleError2<E0, E1>

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> PartialEq for TupleError2<E0, E1>

fn eq(&self, other: &TupleError2<E0, E1>) -> 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.
