Trait Implementations

impl Clone for ProjectionKind

fn clone(&self) -> ProjectionKind

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for ProjectionKind

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

Formats the value using the given formatter.

impl PartialEq<ProjectionKind> for ProjectionKind

fn eq(&self, other: &ProjectionKind) -> 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.

impl Visit for ProjectionKind

fn visit<'v, V>(&'v self, v: &mut V) -> Traversewhere V: Visitor<'v>,
