Trait VisitOutput 

pub trait VisitOutput<Out>: Visit {
    // Required method
    fn finish(self) -> Out;

    // Provided method
    fn visit<R>(self, fields: &R) -> Out
       where R: RecordFields,
             Self: Sized { ... }
}

A visitor that produces output once it has visited a set of fields.

Required Methods

fn finish(self) -> Out

Completes the visitor, returning any output.

This is called once a full set of fields has been visited.

Provided Methods

fn visit<R>(self, fields: &R) -> Out

where R: RecordFields, Self: Sized,

Visit a set of fields, and return the output of finishing the visitor once the fields have been visited.

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
