Function std::ascii::escape_default
[−]
[src]
pub fn escape_default(c: u8) -> EscapeDefault
Returns an iterator that produces an escaped version of a u8
.
The default is chosen with a bias toward producing literals that are legal in a variety of languages, including C++11 and similar C-family languages. The exact rules are:
- Tab, CR and LF are escaped as '\t', '\r' and '\n' respectively.
- Single-quote, double-quote and backslash chars are backslash-escaped.
- Any other chars in the range [0x20,0x7e] are not escaped.
- Any other chars are given hex escapes of the form '\xNN'.
- Unicode escapes are never generated by this function.
Examples
use std::ascii; let escaped = ascii::escape_default(b'0').next().unwrap(); assert_eq!(b'0', escaped); let mut escaped = ascii::escape_default(b'\t'); assert_eq!(b'\\', escaped.next().unwrap()); assert_eq!(b't', escaped.next().unwrap());
