Struct HttpTransport 

pub struct HttpTransport { /* private fields */ }

HTTP transport for communicating with a Haystack server.

Sends requests as encoded grids over HTTP using the configured wire format (default: text/zinc). GET is used for side-effect-free ops; POST for all others.

base_url should be the server API root (e.g. http://localhost:8080/api). auth_token is the bearer token obtained from SCRAM authentication.

pub fn with_format(base_url: &str, auth_token: String, format: &str) -> Self
