# 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

fn main() { 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()); }

    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());

## Search Tricks

Prefix searches with a type followed by a colon (e.g. `fn:`) to restrict the search to a given type.

Accepted types are: `fn`, `mod`, `struct`, `enum`, `trait`, `type`, `macro`, and `const`.

Search functions by type signature (e.g. `vec -> usize`)
