In a typical Rust project you organize your project into many crates. I haven't checked, but I'd guess that the vast majority of those dependencies are internal dependencies. After all, this project started by running an automated C to Rust converter, which the authors claimed produced over a thousand crates.

For what it's worth, Immich supports this too. You can create an album (for each event), create a shared link, allow public anonymous uploads for the shared link, and then give the link to everyone at the event, and ask them to upload their photos. It can be done from any web browser.

It's pretty easy these days to spin up a local Postgres container. Might as well use it for prototyping too, and save yourself the hassle of switching later.

There's a repository setting you can enable to prevent actions from running unless they have their version pinned to a SHA digest. This setting applies transitively, so while you can't force your dependencies to use SHA pinning for their dependencies, you can block any workflow from running if it doesn't.

Pulumi may be what you're looking for. Same concept as Terraform, and many of its provider libraries are just wrappers around Terraform provider libraries, but you can use a variety of common programming languages to declare your desired state, rather than HCL.
