Macro nom::escaped

    (__impl $i: expr, $normal:ident!(  $($args:tt)* ), $control_char: expr, $escapable:ident!(  $($args2:tt)* )) => { ... };

escaped!(T -> IResult<T, T>, U, T -> IResult<T, T>) => T -> IResult<T, T> where T: InputIter, U: AsChar matches a byte string with escaped characters.

The first argument matches the normal characters (it must not accept the control character), the second argument is the control character (like in most languages), the third argument matches the escaped characters

Example

 named!(esc, escaped!(call!(alpha), '\\', one_of!("\"n\\")));
 assert_eq!(esc(&b"abcd;"[..]), Ok((&b";"[..], &b"abcd"[..])));
 assert_eq!(esc(&b"ab\\\"cd;"[..]), Ok((&b";"[..], &b"ab\\\"cd"[..])));
