typecast the &[u8; 4*50_000_000] to a &[f32; 50_000_000]

Be careful about alignment too!

Can i conveniently compile bytes into a Rust program with a specific alignment?

The short version: can I specify the alignment of an include_bytes!("...") invocation? My use case here involves a recent crate I published, regex-automata. One of the key features of that crate is the ability to serialize DFAs to raw bytes and then cheaply deserialize them. In particular, deserialization is designed to be a constant time operation that does no heap allocation or mutation. In other words, a deserialized DFA must be able to operate on the raw bytes, which means that we need to t…
