Implementations§

source§

impl UnOp

source

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

source

pub fn is_by_value(self) -> bool

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

impl<__CTX> HashStable<__CTX> for UnOpwhere __CTX: HashStableContext,

source§

source§

impl PartialEq<UnOp> for UnOp

source§

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

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

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.
