impl<F> Clone for FieldFn<F>

where F: Clone,

fn clone(&self) -> FieldFn<F>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<F> Debug for FieldFn<F>

where F: Debug,

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

Formats the value using the given formatter.

impl<'a, F> MakeVisitor<Writer<'a>> for FieldFn<F>

where F: Fn(&mut Writer<'a>, &Field, &dyn Debug) -> Result<(), Error> + Clone,

type Visitor = FieldFnVisitor<'a, F>
