Function rustc_ast_pretty::pprust::state::space_between

source ยท 
fn space_between(tt1: &TokenTree, tt2: &TokenTree) -> bool
Expand description

Should two consecutive tokens be printed with a space between them?

Note: some old proc macros parse pretty-printed output, so changes here can break old code. For example:

  • #63896: #[allow(unused, must be printed rather than #[allow(unused ,
  • #73345: #[allow(unused)] must be printed rather than # [allow(unused)]
