Enum OneOrBoth

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

A struct indicating either A or B or Both, but not neither - at least one must be present Useful when indicating support for Le or BrEdr, where dual mode is also supported but we require at least one. This avoids extra error checking that would be required if two options were used.

Variants

Left(L)

Both(L, R)

Right(R)

Trait Implementations

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

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

Returns a copy of the value.

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

Performs copy-assignment from source.

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

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

Formats the value using the given formatter.

impl<L: PartialEq, R: PartialEq> PartialEq for OneOrBoth<L, R>

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