Struct HandlerRuntime 

pub struct HandlerRuntime {}

The WebAssembly handler runtime: the shared engine plus the per-site binding backends. Cheap to clone (it is an Arc inside). Without the handlers feature it is an empty placeholder, so the serving signatures stay uniform — pass HandlerRuntime::disabled.

Implementations

impl HandlerRuntime

pub fn disabled() -> Self

An empty runtime — handler dispatch disabled (the static path is unchanged).

pub async fn precompile_component( &self, hash: &str, wasm: &[u8], ) -> Result<(), String>

Precompile an uploaded component blob to warm the compiled-module cache (deploy-resilience #1a), so a later deploy-time introspection / first request finds a cache hit instead of paying a cold cranelift compile on the critical path. Runs no guest code (compile + pre-instantiate only) and is best-effort + concurrency-gated (#2). Always callable; a no-op when this node has no wasm engine. A component that fails to compile is simply not warmed — the deploy that later activates it is the authority that rejects it.
