Function clippy_lints::utils::expr_block [−] [src]

pub fn expr_block<'a, 'b, T: LintContext<'b>>(
    cx: &T, 
    expr: &Expr, 
    option: Option<String>, 
    default: &'a str
) -> Cow<'a, str>

Like snippet_block, but add braces if the expr is not an ExprBlock. Also takes an Option<String> which can be put inside the braces.
