Struct StateId 

pub struct StateId(pub String);

Runtime-state id: state/<kebab> (stage-5 state section, DSL v0.10, spec-0031). A named, scoped, integer-valued datum.

Unlike FlagId this one is declared. A datum’s scope (per-player or party-wide) is a multiplayer semantic that no inference can supply, and a counter — unlike a monotonic “this happened” flag — has an initial value that only a declaration can state.

Implementations

impl StateId

pub const PREFIX: &'static str = "state"

The required type prefix (area, npc, …).

pub fn as_str(&self) -> &str

Borrow the raw id string.

pub fn is_valid_syntax(&self) -> bool

True if the id is well-formed: <prefix>/<kebab>.

pub fn syntax_form(&self) -> String

The form THIS id has to take, for the diagnostic that rejected one — `npc/<kebab>`, `dlg/<kebab>`, and so on.

A refusal that says only “ids must be lowercase kebab-case with their type prefix” and then lists three examples of other types has told the author the general rule and withheld the one fact they were missing: which prefix THIS field takes. The prefix is a property of the id type, so the answer is derived from the type at every site rather than hand-written per site — the per-section refusals that already name their own prefix (wave/, trap/, loot/, …) are that fact copied by hand, which is exactly why the general path never had it.
