}Expand description
A visitor for a Value.
Required Methods§
sourcefn visit_any(&mut self, value: Value<'_>) -> Result<(), Error>
fn visit_any(&mut self, value: Value<'_>) -> Result<(), Error>
Visit a Value.
This is the only required method on Visit and acts as a fallback for any
more specific methods that aren’t overridden.
The Value may be formatted using its fmt::Debug or fmt::Display implementation,
or serialized using its sval::Value or serde::Serialize implementation.
