where Self: Callable,

fn callable_clone(&self) -> Box<dyn Builtin>

impl CallableFormals for KeywordIf

fn formals(&self) -> ExprList

impl Clone for KeywordIf

fn clone(&self) -> KeywordIf

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for KeywordIf

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

Formats the value using the given formatter.

impl Format for KeywordIf

fn rfmt_call_with(&self, _state: FormatState, args: &ExprList) -> String

fn rfmt_with(&self, _state: FormatState) -> String

fn rfmt_infix(s: &str, args: &ExprList) -> String

where Self: Sized,

fn rfmt_infix_with(s: &str, _state: FormatState, args: &ExprList) -> String

where Self: Sized,

fn rfmt(&self) -> String

fn rfmt_call(&self, args: &ExprList) -> String

impl PartialEq for KeywordIf

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