Function clippy_lints::utils::snippet_block
[−]
[src]
pub fn snippet_block<'a, 'b, T: LintContext<'b>>(
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.
