Enum Either 

pub enum Either<L, R> {
    Left(L),
    Right(R),
}

A value that can be one of two types.

Variants

Left(L)

The value is the left type.

Right(R)

The value is the right type.

Trait Implementations

impl<L: Clone, R: Clone> Clone for Either<L, R>

fn clone(&self) -> Either<L, R>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<L: Debug, R: Debug> Debug for Either<L, R>

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

Formats the value using the given formatter.

impl<L: Display, R: Display> Display for Either<L, R>

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

Formats the value using the given formatter.

impl<L: Error + 'static, R: Error + 'static> Error for Either<L, R>

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<L: PartialEq, R: PartialEq> PartialEq for Either<L, R>

fn eq(&self, other: &Either<L, R>) -> 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.
