Subject: [RFC PATCH v3 06/22] rust: capnp: import crate
This is a subset of the Rust `capnp` crate,
version capnpc-v0.18.0, licensed under "MIT", from:
https://github.com/capnproto/capnproto-rust/tree/capnpc-v0.18.0/capnp/src
The files are copied as-is, with no modifications whatsoever
(not even adding the SPDX identifiers).
For copyright details, please see:
https://github.com/capnproto/capnproto-rust/blob/capnpc-v0.18.0/LICENSE
The next patches modify these files as needed for use within the kernel.
This patch split allows reviewers to double-check the import and to
clearly see the differences introduced.
The following script may be used to verify the contents:
for path in $(cd rust/capnp/ && find . -type f -name '*.rs'); do
curl --silent --show-error --location \
https://github.com/capnproto/capnproto-rust/raw/capnpc-v0.18.0/capnp/src/$path \
| diff --unified rust/capnp/$path - && echo $path: OK
done

+//! 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);
+//! }
+//!
