# In order to compile the runtime, including the `proc-macro`s and build scripts, we need the
# required development libraries. These are traditionally provided by `musl-dev` which is not
# inherently included with this image (https://github.com/rust-lang/docker-rust/issues/68). While we
# could install it here, we'd be unable to pin the installed package by its hash as desired.
#
# Rust does have self-contained libraries, intended to be used when the desired development files
# are not otherwise available. These can be enabled with `link-self-contained=yes`. Unfortunately,
# this doesn't work here (https://github.com/rust-lang/rust/issues/149371).
#
# While we can't set `link-self-contained=yes`, we can install Rust's self-contained libraries onto
# our system so they're generally available.
