Enum ProviderBody

pub enum ProviderBody {
    Bynk {
        given: Vec<CapRefIr>,

Expand description

P6.14’s real ProviderBody ([DECISION A], #1174) — referenced by the reference’s own IrItem::Provider sketch (bynk-greenfield-compiler.md:1135, body: ProviderBody // Bynk ops | External(module)) but never defined anywhere in the document as a real Rust type, the same “referenced, not specified” gap Capability’s own OpSig carried before #1173 settled it. Mirrors ProviderDecl::external (bynk-syntax/src/ast.rs:592-595) exactly: true (no brace block, an adapter-supplied binding) becomes External, false (a real Bynk- authored implementation) becomes Bynk. See IrItem’s own doc comment for why External carries no module field despite the reference’s own parenthetical, and why it carries given instead of omitting that too.

Variants§

§

Bynk

A real Bynk-authored implementation.

Fields

§given: Vec<CapRefIr>

ProviderDecl::given, adapted to CapRefIr — needed to build R8.1’s own Provider{Bynk} deps constructor, and not reconstructible from ops alone (IrItem’s own doc comment has the full grounding, review of #1186). In declaration order.

§ops: Vec<ProviderOpIr>

Every operation, bynk_lower::lower_provider_op_ir’s own return value, in declaration order. Not guaranteed non-empty (review of #1186): external is set purely by brace-block absence, not emptiness (bynk-syntax/src/parser/declarations.rs:1795-1811), so provides Cap = P {} also lowers here, with ops: vec![] — the bynk.provider.missing_operation check that would reject it is a whole-project pass (bynk-check/src/project_model.rs:2468), not part of check_provider_decls, so a bare CheckedProgram (this function’s only input) is certified without it.

§

External

provides Cap = Name with no brace block — the adapter’s own binding supplies the implementation; the emitter produces no class (bynk-greenfield-compiler.md:1310, Provider{External} | nothing). Carries given too (added #1187’s Provider given/deps-wiring slice, correcting a real gap this bare-unit shape left): an external provider’s own given clause is populated the same way Bynk’s is (ProviderDecl::given is not gated on external anywhere in the grammar or checker) and instantiate_provider_ts_expr (bynk-emit/src/project.rs) needs it to build an external provider’s own deps constructor argument — this variant’s own doc comment already claimed given “lowers unconditionally” (P6.14’s own review of #1186) before this fix actually made that true.
