Trait Implementations

impl<'a> Clone for Opt<'a>

fn clone(&self) -> Opt<'a>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<'a> Debug for Opt<'a>

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

Formats the value using the given formatter.

impl<'a> PartialEq<Opt<'a>> for Opt<'a>

fn eq(&self, other: &Opt<'a>) -> bool
