Expand description

A runtime resolves environment bindings into Ports and declares statically which ports it can provide, so Harness::build can reject a module that requires something the runtime will never hand it (ADR 0002). Reference implementation: cratefield-runtime-cloudflare.

Required Methods§

Source

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

Provided Methods§

Source

fn effectively_configured(&self, port: Port) -> bool

Whether the named port is not merely present but usable for its production duty (issue #133): a captcha adapter that reports itself unbound cannot protect a HumanForm route, so the runtime that wraps it says “no” here even though provides() lists the port. Default: presence in provides().

Dyn Compatibility§

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
