Escrow program using Anchor (for learning the best practice) Escrow program using vanilla Rust (for learning core concepts)ģ. ![]() (), a specialized PBFT designed for PoH Efficient network synchronization using () **Parallelism is the secret sauce** making it blazing fast # Compare Solana to Ethereum, what are the pros and cons? (Almost) every programmable blockchain has a rust implementation It's a good investment on modern web technology (Rust / Typescript, etc) It's blazing fast and efficient, meaning it will be cheap and affordable for average users It's a new blockchain paradigm evolved from Ethereum (more or less) What is the best practice to develop Solana programs? How can I setup my the environment quickly? What should I learn at minimum to understand how Solana program works? What makes Solana so fast and efficient?

RUST CONVERT MAC ADDRESS TO U8 HOW TOI assume you are already aware of the issues with naively sending bytes around (like potential endianness issues or versioning), but I'll mention them just in case ^_^.# How to get onboard to Solana develepement quickly? You would then be able to send the bytes wherever you want. Let bytes = bincode::serialize(&a).unwrap() Let mut f = File::create("/tmp/output.bin").unwrap() īincode::serialize_into(&mut f, &a).unwrap() Encode to something implementing `Write` Heres a working example based on the question: unsafe fn any_as_u8_slice(p: &T) -> & Note that the question asks about converting, this example creates a read-only slice, so has the advantage of not needing to copy the memory. In the example below there there is a reusable function called any_as_u8_slice instead of convert_struct, since this is a utility to wrap cast and slice creation. A correctly sized struct as zero-copied bytes can be done using stdlib and a generic function. ![]()
