Extension trait providing MakeVisitor combinators.

Provided Methods

fn debug_alt(self) -> Alt<Self>

Wraps self so that any fmt::Debug fields are recorded using the alternate formatter ({:#?}).

fn display_messages(self) -> Messages<Self>

Wraps self so that any string fields named “message” are recorded using fmt::Display.

fn delimited<D>(self, delimiter: D) -> Delimited<D, Self>

where D: AsRef<str> + Clone, Self::Visitor: VisitFmt,

Wraps self so that when fields are formatted to a writer, they are separated by the provided delimiter.
