# `serde` is the only optional integration usable on a bare-metal target. It is wired as a
# core-only dependency (`default-features = false`) and picks up serde's `alloc`/`std` layers
# only when this crate's own `alloc`/`std` features are on, via weak `serde?/..` features.
serde = ["dep:serde"]
# `utoipa` and `clap` both imply `std`. Their derive macros expand to `std::`, `String` and
# `Vec` paths inside this crate, which cannot compile under `#![no_std]`.
#
# `utoipa` additionally implies `serde`, because a `ToSchema` describes this crate's *serde*
# representation: several types serialize as a single protocol byte rather than as their Rust
# shape, and their schemas are written to match. A `utoipa`-without-`serde` build would therefore
# publish a schema for a wire format that build cannot produce. It also cost real complexity —
# every type reachable only through a serde repr needed a second cfg predicate and a
# `allow(dead_code)` to stay compilable in a configuration nobody wants.
