Expand description

This trait is used for both AST and HIR pretty-printing.

Required Methods§

source

fn comments(&mut self) -> &mut Option<Comments<'a>>

source

fn ann_post(&mut self, ident: Ident)

source

fn print_generic_args(&mut self, args: &GenericArgs, colons_before_params: bool)

Provided Methods§

source

fn print_ident(&mut self, ident: Ident)

source

fn strsep<T, F>( &mut self, sep: &'static str, space_before: bool, b: Breaks, elts: &[T], op: F )
where F: FnMut(&mut Self, &T),

source

fn commasep<T, F>(&mut self, b: Breaks, elts: &[T], op: F)
where F: FnMut(&mut Self, &T),

fn print_comment(&mut self, cmnt: &Comment)

source

fn next_comment(&mut self) -> Option<Comment>

source

fn maybe_print_trailing_comment( &mut self, span: Span, next_pos: Option<BytePos> )

source

fn print_attr_item(&mut self, item: &AttrItem, span: Span)

source

fn print_tt(&mut self, tt: &TokenTree, convert_dollar_crate: bool) -> Spacing

This doesn’t deserve to be called “pretty” printing, but it should be meaning-preserving. A quick hack that might help would be to look at the spans embedded in the TTs to decide where to put spaces and newlines. But it’d be better to parse these according to the grammar of the appropriate macro, transcribe back into the grammar we just parsed from, and then pretty-print the resulting AST nodes (so, e.g., we print expression arguments as expressions). It can be done! I think.
