Trait BorrowFromCp437

pub trait BorrowFromCp437<'c, T: ?Sized> {
    // Required method
    fn borrow_from_cp437(cp437: &'c T, dialect: &Cp437Dialect) -> Self;
}

Try to borrow data encoded in cp437 as a Unicode container of the specified type.

If that cannot be done, clone it.

Examples

let cp437 = [0x4C, 0x6F, 0x63, 0x61, 0x6C, 0x20, 0x6E, 0x65, 0x77, 0x73, 0x20, 0x72, 0x65,
             0x70, 0x6F, 0x72, 0x74, 0x73, 0x20, 0x74, 0x68, 0x61, 0x74, 0x20, 0x74, 0x68,
             0x65, 0x20, 0x9E, 0xAB, 0x20, 0x6D, 0x69, 0x6C, 0x6C, 0x69, 0x6F, 0x6E, 0x20,
             0x41, 0x69, 0x72, 0x20, 0x4D, 0x65, 0x6C, 0x61, 0x6E, 0x65, 0x73, 0x69, 0x91,

             0x6E, 0x64, 0x20, 0x39, 0x3A, 0x30, 0x30, 0x61, 0x6D, 0x2E];
let unicode = "Local news reports that the ₧½ million Air Melanesiæ aircraft has crashed this morning around 9:00am.";

assert_eq!(Cow::borrow_from_cp437(&cp437[..], &CP437_CONTROL),
           String::borrow_from_cp437(&cp437[..], &CP437_CONTROL));
assert_eq!(Cow::borrow_from_cp437(&cp437[..], &CP437_CONTROL), unicode);

Required Methods

fn borrow_from_cp437(cp437: &'c T, dialect: &Cp437Dialect) -> Self

Do the conversion.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
