Compiler errors due to unstable / experimental features

[nocko]

I couldn't find dockcross-linux-armv7-rust, so I attempted to build this way:

docker run --rm -v c:\\Users\\nock\\devel\\plato:/work rustcross/arm-unknown-linux-gnueabihf:latest ./build.sh

It builds most of the dependencies, but then bails on unstable / experimental features:

error: `pub(restricted)` syntax is experimental (see issue #32409)
  --> /root/.cargo/registry/src/github.com-1ecc6299db9ec823/crockford-1.0.1/src/error.rs:15:9

   |         ^^^^^

error: struct field shorthands are unstable (see issue #37340)

Do you have time to jot a few notes on how to build this project?
