Struct Http 

pub struct Http { /* private fields */ }

http: reaching a server, and being one.

Implementations

impl Http

pub fn real() -> Self

A host that speaks HTTP/1.1 over TCP.

listen binds loopback only. Granting http is authority to talk to the machine’s own network stack, not permission to publish a service on every interface the machine has.

pub fn recorded( answers: BTreeMap<String, RecordedResponse>, requests: Vec<ScriptedRequest>, ) -> Self

A fake that answers fetch from answers and lets a listener replay requests, for tests.

The key is the URL exactly as the program writes it. This is a recorded answer, not a client: a fake that resolved a host name would be reaching the network the grant was supposed to describe.

pub fn served(&self) -> Served

What this host has served so far, for a test to read back.

A real host serves to a socket and keeps nothing, so it answers with an empty log: what went out is on the other end of the connection.

pub fn denied() -> Self

A host with no network, which refuses every call and says so.

Trait Implementations

impl HostApi for Http

fn call_with( &self, op: &str, args: Vec<Value>, back: &mut dyn Reentry, ) -> Result<Value, RuntimeError>

fetch is the one module-level operation that waits, so it is the one that needs the way back: not to run a callback, but to ask how long the run it belongs to still has and whether it has been told to stop. Everything else here touches only what it was given.

fn module_schema(&self) -> ModuleSchema

The whole of what this module declares about itself: the name Cove source uses, the capability a host must grant for it, the operations it exposes, the types it declares, and the kinds of resource it can open.

fn call(&self, op: &str, args: Vec<Value>) -> Result<Value, RuntimeError>

Invokes one operation.

fn call_resource( &self, handle: &ResourceHandle, op: &str, args: Vec<Value>, back: &mut dyn Reentry, ) -> Result<Value, RuntimeError>

Invokes one operation on a handle this module issued.
