Trait to implement for language specialization.

The various language implementations can be found in the lang module.

Required Associated Types

type Config

Configuration associated with building a formatting element.

type Format: Default

State being used during formatting.

type Item: LangItem<Self>

The type used when resolving imports.

Provided Methods

fn default_indentation() -> Indentation

Provide the default indentation.

fn open_quote( out: &mut Formatter<'_>, _config: &Self::Config, _format: &Self::Format, _has_eval: bool ) -> Result

Start a string quote.

fn close_quote( out: &mut Formatter<'_>, _config: &Self::Config, _format: &Self::Format, _has_eval: bool ) -> Result

End a string quote.

fn string_eval_literal( out: &mut Formatter<'_>, config: &Self::Config, format: &Self::Format, literal: &str ) -> Result

A simple, single-literal string evaluation.

fn start_string_eval( _out: &mut Formatter<'_>, _config: &Self::Config, _format: &Self::Format ) -> Result

Start a string-interpolated eval.

fn end_string_eval( _out: &mut Formatter<'_>, _config: &Self::Config, _format: &Self::Format ) -> Result

End a string interpolated eval.

fn write_quoted(out: &mut Formatter<'_>, input: &str) -> Result

Performing string quoting according to language convention.

fn format_file( tokens: &Tokens<Self>, out: &mut Formatter<'_>, config: &Self::Config ) -> Result

Write a file according to the specified language convention.
