Enum rustc_hir::hir::UnOp

pub enum UnOp {
    Deref,
    Not,
    Neg,
}

Unary operator.

Note that &data is not an operator, it’s an AddrOf expression.

Variants

Deref

The * operator for dereferencing

Not

The ! operator for logical inversion

Neg

The - operator for negation

Implementations

impl UnOp

pub fn as_str(&self) -> &'static str

pub fn is_by_value(self) -> bool

Returns true if the unary operator takes its argument by value.

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<(), Error>

Formats the value using the given formatter.

impl<__D> Decodable<__D> for UnOp

where __D: SpanDecoder,

fn decode(__decoder: &mut __D) -> UnOp

impl<__E> Encodable<__E> for UnOp

where __E: SpanEncoder,

fn encode(&self, __encoder: &mut __E)

impl<__CTX> HashStable<__CTX> for UnOp

where __CTX: HashStableContext,

fn hash_stable( &self, __hcx: &mut __CTX, __hasher: &mut StableHasher<SipHasher128>, )

impl PartialEq for UnOp

fn eq(&self, other: &UnOp) -> 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 Copy for UnOp

impl StructuralPartialEq for UnOp

Layout

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
