Struct HttpAdapter 

pub struct HttpAdapter { /* private fields */ }

The HTTP adapter: executes ops as HTTP requests.

Implementations

impl HttpAdapter

pub fn new() -> Self

Create with default config.

pub fn with_config(config: HttpConfig) -> Self

Create with explicit config.

Trait Implementations

impl Default for HttpAdapter

fn default() -> Self

Returns the “default value” for a type.

impl DriverAdapter for HttpAdapter

fn known_op_fields(&self) -> Option<&'static [&'static str]>

HTTP adapter reads a closed vocabulary of op fields: request-shape (method, uri / url), body framing (content_type, body), and header overrides (headers). Declaring the list opts this adapter into SRD 30’s unknown-field guard — typos like bdoy: or misplaced core directives surface at init time rather than silently becoming ResolvedFields the adapter never looks at.

fn name(&self) -> &str

Human-readable adapter name (e.g., “cql”, “http”, “stdout”).

fn map_op<'a>( &'a self, template: &'a ParsedOp, parent: Arc<dyn Kernel>, ) -> Pin<Box<dyn Future<Output = Result<Box<dyn OpDispenser>, String>> + Send + 'a>>

Map an op template into a dispenser. Called once per unique op template at activity startup — before any cycles execute.

fn default_status_metrics(&self) -> Vec<StatusMetric>

Default metric names to display on the status line for this adapter.

fn display_preference(&self) -> DisplayPreference

Preferred display mode for this adapter.

fn known_op_params(&self) -> &'static [&'static str]

Adapter-specific params keys allowed under an op’s top-level params (not op) section. Returned keys extend the core’s crate::validation::CORE_OP_PARAMS allow-list at op-validation time. Default: empty — adapters that don’t need extras simply rely on the core vocab. Override to declare adapter-only params (e.g. CQL’s cl: consistency-level overrides if those were lifted from op to params someday).

fn declare_controls(&self, _parent: &Arc<RwLock<Component>>)

Declare adapter-specific dynamic controls (SRD 23) on a subcomponent attached to the activity’s component. Called once per activity, after the activity declares its own concurrency / rate controls. The default no-op fits adapters that have no adapter-level dynamic knobs.

fn shutdown<'a>(&'a self) -> Pin<Box<dyn Future<Output = ()> + Send + 'a>>

Async teardown hook fired by the resource pool when a shared adapter’s last reference detaches (or at session shutdown). Default: no-op — drop is enough for adapters whose underlying driver closes synchronously in its destructor.

fn accessor_payload(&self) -> Option<Arc<dyn Any + Send + Sync>>

SRD-104 — the adapter’s accessor payload: a type-erased handle (Arc<dyn Any + Send + Sync>) a kernel node can obtain by fingerprint through its kernel tree’s resource scope (ResourceScope::lookup). The resource pool surfaces this through crate::resource_pool::SharedResource::accessor_payload (the pool-shared wrapper delegates here) and stores it on the entry at init. Default None — an adapter opts in only when it wants kernels to reach a live handle (the first consumer is the CQL session handle, SRD-103). Built over the adapter’s own connected session, so the payload and the op-execution path share one resource.
