Create Solana programs with no dependencies attached.

I've got no dependencies

To hold me down

To make me fret

Or make me frown

I had dependencies

But now I'm free

There are no dependencies on me

Pinocchio is a zero-dependency library to create Solana programs in Rust. It takes advantage of the way SVM loaders serialize the program input parameters into a byte array that is then passed to the program's entrypoint to define zero-copy types to read the input. Since the communication between a program and SVM loader — either at the first time the program is called or when one program invokes the instructions of another program — is done via a byte array, a program can define its own types. This completely eliminates the dependency on the solana-program crate, which in turn mitigates dependency issues by having a crate specifically designed to create on-chain programs.

As a result, Pinocchio can be used as a replacement for solana-program to write on-chain programs, which are optimized in terms of both compute units consumption and binary size.
