Trait Visitor 

pub trait Visitor<'a, T>: Sized {
    // Required method
    fn accept(scanner: &mut Scanner<'a, T>) -> ParseResult<Self>;
}

A Visitor is a trait that allows to define how to visit a Scanner.

When a Visitor is used on a Scanner, it will consume the input from the scanner and return the result of the visit.

Type Parameters

• T - The type of the data to visit.

Associated Functions

• accept - Try to accept the Scanner and return the result of the visit.

Required Methods

fn accept(scanner: &mut Scanner<'a, T>) -> ParseResult<Self>

Try to accept the Scanner and return the result of the visit.

Arguments

• scanner - The scanner to accept.

Returns

The result of the visit.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
