Trait Formatter

pub trait Formatter: FormatWriter {
    // Provided methods
    fn block(&mut self, f: impl Fn(&mut Self) -> Result) -> Result { ... }
    fn write_token(&mut self, token: impl Display) -> Result { ... }
    fn write_show(&mut self, item: impl ZonefileFmt) -> Result { ... }
    fn write_comment(&mut self, s: impl Display) -> Result { ... }
}

A more structured wrapper around a [PresentationWriter]

Provided Methods

fn block(&mut self, f: impl Fn(&mut Self) -> Result) -> Result

Start a sequence of grouped tokens

The block might be surrounded by ( and ) in a multiline format.

fn write_token(&mut self, token: impl Display) -> Result

Push a token

fn write_show(&mut self, item: impl ZonefileFmt) -> Result

Call the show method on item with this Presenter

fn write_comment(&mut self, s: impl Display) -> Result

Write a comment

This may be ignored.

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.
