A Rust implementation of Android's Binder

Linux is rather badly suited for IPC heavy architectures, since it exactly lacks an IPC mechanism, which does not shovel data through the kernel and at the same time provides sufficient security and abstractions, which simple shared memory is lacking.
In addition, binder originally was intended as an IPC mechanism, with implicit control flow changes (true RPC), which is something every microkernel offers, but linux historically lacked.
I am not sure, if binder still behaves that way, with all shift towards more of its code running in userspace, though.
