Struct HttpSigningAdapter 

pub struct HttpSigningAdapter { /* private fields */ }

A SigningPort that delegates to an external HTTP signing sidecar.

The sidecar receives a JSON payload describing the outbound request and returns the headers / query params / body override to apply. This pattern works for:

• Frida RPC bridges — a Python/Node sidecar attached to a running mobile app that calls the native .so signing function and exposes the result
• AWS Signature V4 — a lightweight server that knows your AWS credentials
• OAuth 1.0a — sign Twitter/X API v1 requests via a sidecar that holds the consumer secret
• Any custom HMAC scheme — keep key material out of the main process

Example

use stygian_graph::adapters::signing::{HttpSigningAdapter, HttpSigningConfig};
use stygian_graph::ports::signing::{SigningPort, SigningInput};
use serde_json::json;

let signer = HttpSigningAdapter::new(HttpSigningConfig {
    endpoint: "http://localhost:27042/sign".to_string(),
    ..Default::default()
});

let output = signer.sign(SigningInput {
    method: "GET".to_string(),
    url: "https://api.tinder.com/v2/profile".to_string(),
    headers: Default::default(),
    body: None,
    context: json!({}),
}).await.unwrap();

for (k, v) in &output.headers {
    println!("{k}: {v}");
}

Implementations

impl HttpSigningAdapter

pub fn new(config: HttpSigningConfig) -> Self

Create a new HttpSigningAdapter with the given configuration.

Example

use stygian_graph::adapters::signing::{HttpSigningAdapter, HttpSigningConfig};

let signer = HttpSigningAdapter::new(HttpSigningConfig::default());

Trait Implementations
