Struct Handler 

pub struct Handler { /* private fields */ }

The worker side of an invocation, for any HTTP framework: give it the request’s fusee-signature header and body, answer with its Reply. Each call opens a fresh engine and closes it before it returns; nothing is kept between invocations.

Implementations

impl Handler

pub fn new( address: impl Into<String>, secret: impl AsRef<[u8]>, register: impl Fn(&Engine) + Send + Sync + 'static, ) -> Result<Self>

address: the server, with this worker’s connection options (host:port?ca=...&token-file=...). secret: the endpoint’s signing secret. register: registers the workflows on each fresh engine.

pub fn unsigned( address: impl Into<String>, register: impl Fn(&Engine) + Send + Sync + 'static, ) -> Self

Accepts unsigned requests: only behind mutual TLS (serve with a CA) or on a network only the server reaches.

pub fn configure(self, f: impl Fn(&mut Config) + Send + Sync + 'static) -> Self

Adjusts each engine’s configuration before it opens.

pub async fn handle(&self, signature: Option<&str>, body: &[u8]) -> Reply

Checks the signature and runs the invocation: 200 with a summary, 401 for a bad signature, 400 for a bad body, 503 when the server cannot be reached.

pub async fn invoke(&self, request: &Request) -> Result<Value>

Runs a verified invocation; the summary is the 200 reply’s body.
