pub fn check<T, U>(v1: T, v2: U) -> Result<RbEncoding, Error>where
T: EncodingCapable,
U: EncodingCapable,Expand description
Returns the common encoding between v1 and v2, or Err.
Returns Err if there is no common compatible encoding.
See also compatible.
Examples
use magnus::{encoding::{self, EncodingCapable}, RString};
let a = RString::new("a");
let b = RString::new("b");
assert!(a.enc_get() == encoding::Index::utf8());
b.enc_set(encoding::Index::usascii());
assert_eq!(encoding::check(a, b).unwrap().name(), "UTF-8");
