//! Conversions between Rust strings/slices and the v2 C API string types.

//! These live in the sys crate because the orphan rule prevents a downstream
//! wrapper from implementing `From`/`Default` for the bindgen-generated types.

// Only Rust-to-C conversions live here: building a raw string is safe, reading through one is not.
