Trait Implementations

impl Clone for JoinOptions

fn clone(&self) -> JoinOptions

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for JoinOptions

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

Formats the value using the given formatter.

impl Default for JoinOptions

fn default() -> JoinOptions

Returns the “default value” for a type.

impl PartialEq<JoinOptions> for JoinOptions

fn eq(&self, other: &JoinOptions) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
