pub fn escape(bytes: &[u8]) -> String
Expand description
Escapes arbitrary bytes into a human readable string.
This converts \t
, \r
and \n
into their escaped forms. It also
converts the non-printable subset of ASCII in addition to invalid UTF-8
bytes to hexadecimal escape sequences. Everything else is left as is.
The dual of this routine is unescape
.
Example
This example shows how to convert a byte string that contains a \n
and
invalid UTF-8 bytes into a String
.
Pay special attention to the use of raw strings. That is, r"\n"
is
equivalent to "\\n"
.
use grep_cli::escape;
assert_eq!(r"foo\nbar\xFFbaz", escape(b"foo\nbar\xFFbaz"));
