Trait Implementations

impl Clone for UnOp

fn clone(&self) -> UnOp

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for UnOp

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

Formats the value using the given formatter.

impl Display for UnOp

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

Formats the value using the given formatter.

impl Hash for UnOp

fn hash<H: Hasher>(&self, state: &mut H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Parse for UnOp

fn parse(input: ParseStream<'_>) -> Result<Self>

impl PartialEq for UnOp

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

impl Spanned for UnOp

fn span(&self) -> Span

Returns a Span covering the complete contents of this syntax tree node, or Span::call_site() if this node is empty.

fn set_span(&mut self, span: Span)

Sets the span of this syntax tree node if it is not empty.

fn with_span(self, span: Span) -> Self

where Self: Sized,

Sets the span of this owned syntax tree node if it is not empty.

impl Copy for UnOp

impl Eq for UnOp
