Function clippy_utils::source::expr_block

pub fn expr_block<T: LintContext>(
    cx: &T,
    expr: &Expr<'_>,
    outer: SyntaxContext,
    default: &str,
    indent_relative_to: Option<Span>,
    app: &mut Applicability
) -> String

Like snippet_block, but add braces if the expr is not an ExprKind::Block.
