Trait Implementations

impl Clone for UnaryExpr

fn clone(&self) -> UnaryExpr

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for UnaryExpr

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

Formats the value using the given formatter.

impl Display for UnaryExpr

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

Formats the value using the given formatter.

impl PartialEq for UnaryExpr

fn eq(&self, other: &UnaryExpr) -> 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 Prettier for UnaryExpr

fn pretty(&self, level: usize, max: usize) -> String

max param is short for max_characters_per_line.

fn format(&self, level: usize, _max: usize) -> String

override format if expr needs to be split into multiple lines

fn needs_split(&self, max: usize) -> bool

override needs_split to return false, in order not to split multiple lines
