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.

Trait Implementations

source

impl Clone for UnOp

source

fn clone(&self) -> UnOp

Returns a copy of the value. Read more

1.0.0 · source

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

Performs copy-assignment from source. Read more

source

impl Debug for UnOp

source

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

Formats the value using the given formatter. Read more

source

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

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