/*!
Objective-C type encoding creation and parsing in Rust.

The Objective-C compiler encodes types as strings for usage in the runtime.
This crate aims to provide a strongly-typed (rather than stringly-typed) way
to create and describe these type encodings without memory allocation in Rust.

# Implementing Encode

This crate declares an `Encode` trait that can be implemented for types that
the Objective-C compiler can encode. Implementing this trait looks like:

``` ignore
unsafe impl Encode for CGPoint {
    const ENCODING: Encoding<'static> =
        Encoding::Struct("CGPoint", &[CGFloat::ENCODING, CGFLOAT::ENCODING]);
}
```

For an example of how this works with more complex types, like structs
containing structs, see the `core_graphics` example.

# Comparing with encoding strings

An `Encoding` can be compared with an encoding string from the Objective-C
runtime:

```
# use objc_encode::Encode;
assert!(&i32::ENCODING == "i");
```

# Generating encoding strings

Every `Encoding` implements `Display` as its string representation.
This can be generated conveniently through the `to_string` method:

```
# use objc_encode::Encode;
assert_eq!(i32::ENCODING.to_string(), "i");
```
