Struct Ports 

pub struct Ports {

    pub config: Arc<dyn Config>,
    pub db: Option<Arc<dyn Database>>,
    pub mailer: Option<Arc<dyn Mailer>>,
    pub captcha: Option<Arc<dyn Captcha>>,
    pub rate_limiter: Option<Arc<dyn RateLimiter>>,

    pub realtime: Option<Arc<dyn Realtime>>,
    pub http: Option<Arc<dyn HttpClient>>,
    pub clock: Option<Arc<dyn Clock>>,
    pub id_gen: Option<Arc<dyn IdGen>>,
    pub defer: Option<Arc<dyn Defer>>,
    pub dispatcher: Option<Arc<dyn Dispatcher>>,
    pub tenants: Option<Arc<dyn TenantRouting>>,
}

The per-request bundle of resolved port implementations plus the typed config the runtime built from environment/secrets.

Every port is optional: the Cloudflare runtime resolves what the venture’s bindings actually provide and leaves the rest None.

Fields

config: Arc<dyn Config>

db: Option<Arc<dyn Database>>

mailer: Option<Arc<dyn Mailer>>

captcha: Option<Arc<dyn Captcha>>

rate_limiter: Option<Arc<dyn RateLimiter>>

signer: Option<Arc<dyn Signer>>

kv: Option<Arc<dyn KeyValue>>

blob: Option<Arc<dyn Blob>>

push: Option<Arc<dyn Push>>

payments: Option<Arc<dyn Payments>>

realtime: Option<Arc<dyn Realtime>>

http: Option<Arc<dyn HttpClient>>

clock: Option<Arc<dyn Clock>>

id_gen: Option<Arc<dyn IdGen>>

defer: Option<Arc<dyn Defer>>

dispatcher: Option<Arc<dyn Dispatcher>>

Set by the runtime when the venture mounts sidecar modules. Not a Port, so view_for never copies it and no module can reach it.

tenants: Option<Arc<dyn TenantRouting>>

How this deployment turns a host into a tenant, and a tenant into its database (TENANT-ROUTING.md §3-§5). None is the no registry deployment — Cloudflare, the browser, and native in development and test — which resolves every host to the implicit tenant and hands back Ports::db.

Not a Port for the same reason dispatcher is not: view_for must never copy it into a module’s view. A module reaches a database through the TenantConn extractor, which can only give it the one the request resolved.

Implementations

impl Ports

pub fn empty() -> Self

An empty bundle with no ports resolved and an EmptyConfig.

pub fn with_config(config: Arc<dyn Config>) -> Self

pub fn provides(&self) -> Vec<Port>

The set of ports this bundle actually provides.

pub fn view_for(&self, module: &dyn Module) -> Self

A copy of this bundle in which every port the module did not declare in requires() or optional() is None, so a module cannot use what it did not declare (issue #3). Undeclared-but-provided ports are logged once per module by Harness::build.
