The process of how a 0x0A byte is inserted into a file named bar in a justfile using Rust and OCaml compilers is dissected. Just, written in Rust, relies on cook_string to evaluate escape sequences and ends up delegating to rustc, which eventually handles the n character escape as a 0x0A byte. The lineage of […]
