// ---------------------------------------------------------------------------------------------
// Contract attributes used throughout this header:
//
// `gnu::pure` marks a function that reads memory (through its arguments and through globals) but
// writes nothing observable, so the compiler may cache and reorder calls to it. It is applied to
// the comparison / search accessors, and deliberately NOT to:
// * the `To*` converters -- `strtod` / `strtoull` / `strtoll` write `errno`;
// * `ffStrbufEndsWithFn` -- the caller-supplied `fn` may have side effects;
// * `ffStrbufWriteTo` / `ffStrbufPutTo` -- they write to a `FILE*`.
//
// `gnu::nonnull(N)` is added wherever the function dereferences argument N unconditionally. The
// two cannot be combined with a null check: clang reports `-Wtautological-pointer-compare` /
// `-Wpointer-bool-conversion` (both in `-Wall`) when a `nonnull` parameter is compared against
// null, so a redundant `assert(p != nullptr)` is dropped in favour of the attribute. Asserts that
// state something `nonnull` cannot express -- pointer aliasing (`value != strbuf`), index ranges
// (`start <= strbuf->length`), or a non-pointer invariant -- are kept.
//
// `nodiscard` is NOT applied to the "was the buffer modified" boolean returns
// (`ffStrbufSubstr*`, `ffStrbufRemoveSubstr`, `ffStrbufEnsureEndsWithC`, ...). Ignoring that
// result is a normal, intended use of those functions -- `ffStrbufSubstrBefore` alone has 153 call
// sites and ~147 of them discard the result -- so `nodiscard` would only produce noise.
