This is a subset of the Rust standard library `alloc` crate,
version 1.60.0, licensed under "Apache-2.0 OR MIT", from:
https://github.com/rust-lang/rust/tree/1.60.0/library/alloc/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/rust-lang/rust/blob/1.60.0/COPYRIGHT
The next patch modifies 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.
Vendoring `alloc`, at least for the moment, allows us to have fallible
allocations support (i.e. the `try_*` versions of methods which return
a `Result` instead of panicking) early on. It also gives a bit more
freedom to experiment with new interfaces and to iterate quickly.
Eventually, the goal is to have everything the kernel needs in
upstream `alloc` and drop it from the kernel tree.
For a summary of work on `alloc` happening upstream, please see:
