Function clippy::utils::snippet_block

pub fn snippet_block<'a, T: LintContext>(cx: &T, span: Span, default: &'a str) -> Cow<'a, str>

Convert a span (from a block) to a code snippet if available, otherwise use default. This trims the code of indentation, except for the first line. Use it for blocks or block-like things which need to be printed as such.

Example

snippet(cx, expr.span, "..")
