Function url::percent_encoding::percent_encode

pub fn percent_encode<E: EncodeSet>(input: &[u8],
                                    encode_set: E)
                                    -> PercentEncode<E>

Percent-encode the given bytes with the given encode set.

The encode set define which bytes (in addition to non-ASCII and controls) need to be percent-encoded. The choice of this set depends on context. For example, ? needs to be encoded in an URL path but not in a query string.

The return value is an iterator of &str slices (so it has a .collect::<String>() method) that also implements Display and Into<Cow<str>>. The latter returns Cow::Borrowed when none of the bytes in input are in the given encode set.
