# Function rustc_ast_pretty::pprust::state::space_between

source ·

    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)]`
