+//! Untyped root container for a Cap'n Proto value.
+//!
+//! ## Notes about type specialization
+//! This module provides [TypedReader] and [TypedBuilder] structs which are strongly-typed variants
+//! of [Reader] and [Builder].
+//!
+//! Code autogenerated by capnpc will have an individual module for each of structures and each of
+//! modules will have `Owned` struct which implements [Owned] trait.
+//!
+//! Example from a real auto-generated file:
+//!
+//! ```ignore
+//! pub mod simple_struct {
+//!     #[derive(Copy, Clone)]
+//!     pub struct Owned(());
+//!     impl <'a> ::capnp::traits::Owned<'a> for Owned { type Reader = Reader<'a>; type Builder = Builder<'a>; }
+//!     ....
+//! }
+//! ```
+//!
+//! [TypedReader] and [TypedBuilder] accept generic type parameter `T`. This parameter must be
+//! a corresponding `Owned` type which was auto-generated inside the corresponding module.
+//!
+//! For example, for auto-generated module `crate::test_data::simple_struct` you'd supply
+//! `crate::test_data::simple_struct::Owned` type into [TypedReader]/[TypedBuilder]
+//!
+//! ```ignore
+//! include!(concat!(env!("OUT_DIR"), "/simple_struct_capnp.rs"));
+//!
+//! use capnp::message::{self, TypedBuilder, TypedReader};
+//!
+//! fn main() {
+//!     let mut builder = TypedBuilder::<simple_struct::Owned>::new_default();
+//!     let mut builder_root = builder.init_root();
+//!     builder_root.set_x(10);
+//!     builder_root.set_y(20);
+//!
+//!     let mut buffer = vec![];
+//!     capnp::serialize_packed::write_message(&mut buffer, builder.borrow_inner()).unwrap();
+//!
+//!     let reader = capnp::serialize_packed::read_message(buffer.as_slice(), ReaderOptions::new()).unwrap();
+//!     let typed_reader = TypedReader::<_, simple_struct::Owned>::new(reader);
+//!
+//!     let reader_root = typed_reader.get().unwrap();
+//!     assert_eq!(reader_root.get_x(), 10);
+//!     assert_eq!(reader_root.get_x(), 20);
+//! }

+/// A trait to encode relationships between readers and builders.
+///
+/// If `Foo` is a Cap'n Proto struct and `Bar` is a Rust-native struct, then
+/// `foo::Reader<'a>` is to `foo::Owned` as `&'a Bar` is to `Bar`, and
+/// `foo::Builder<'a>` is to `foo::Owned` as `&'a mut Bar` is to `Bar`.
+/// The relationship is formalized by an `impl capnp::traits::Owned for foo::Owned`.
+/// Because Cap'n Proto struct layout differs from Rust struct layout, a `foo::Owned` value
+/// cannot be used for anything interesting on its own; the `foo::Owned` type is useful
+/// nonetheless as a type parameter, e.g. for a generic container that owns a Cap'n Proto
+/// message of type `T: capnp::traits::Owned`.
