Enum ModeKind 

pub enum ModeKind {
    Major,
    Minor,
}

Major / minor distinction. A buffer has exactly one major and any number of minors active simultaneously (mode-architecture.md §3).

Variants

Major

Content-type identity (rust-mode, help-mode). Exactly one per buffer; activating another replaces it. Chosen by the host’s major resolver (Mode::target_buffer_kind, Mode::target_language, Mode::presents_extensions), never by an ActivationPolicy.

Minor

Additive behaviour layered over the major (line-numbers-mode, table-mode). Any number per buffer, kept in activation order; auto-activated per Mode::activation_policy or pulled in by another mode’s Mode::implies.
