C for Rust programmers highlights quirks Rust developers may not expect

bd103.dev 10 min read Editor score 6/10

The guide introduces C concepts that may surprise Rust programmers, including the history of boolean support and the optional `stdbool.h` header. It can help systems engineers moving between the languages, but is explicitly not a full C tutorial.

What

C for Rust Programmers is a guide to C details that may surprise developers whose first systems language was Rust.

How

C strings end with a null byte instead of storing a separate length; forgetting the terminator can cause out-of-bounds reads.

Why it matters

Engineers working across low-level languages need to account for C string allocation and termination to avoid memory errors.
