i need to have a nightly build of rust but it doesnt allow me to do that with cargo and rustup does not exist.

Did u try creating a rust-toolchain.toml and adding to it?

[toolchain]
channel = "nightly"

[toolchain]
channel = "nightly"

nightly versions are set in this file instead of cargo

Then i'm afraid you can't do that with Nixpacks

App source + Nix packages + Docker = Image

which is weird 'cause the rust-toolchain.toml file is mentioned in the docs... which also makes me think that something else may be the issue
