1//! File-kind classification for a `TextBuffer`.

3//! Owns the three flags that describe "what sort of file is this":
4//! large-file mode (lazy chunked loading), whether the line-feed scan
5//! has run over it, and whether the content is binary (read-only,
6//! rendered as code points). Composed inside `TextBuffer` as the
7//! `file_kind` field.
