All the answers to this question about passing an array from C to Rust use std::slice::from_raw_parts to convert the raw C pointer and some length information into a Rust. In an embedded context (MOS 6502 in my case), there might not be a std library available. So in a #![no_std] context, what is the nicest way of passing an array from C to Rust for (potentially mutable) processing?

While
std::slice::from_raw_partsis not available in ano_stdenvironment,core::slice::from_raw_partsis available, so you can simply use that.In general, anything that is in
stdand not somehow platform dependent (so, not I/O, heap allocation and the like) should also be available inno_stdenvironments through thecorecrate.
