Struct HttpClient 

pub struct HttpClient {
    pub default_headers: BTreeMap<String, String>,
    pub timeout_ms: u64,
    pub max_redirects: u8,
}

HTTP client with configurable defaults.

The client does not perform actual I/O. Instead, prepare_request() returns serialized bytes to send over TCP, and parse_response() accepts received bytes and returns an HttpResponse when complete.

Fields

default_headers: BTreeMap<String, String>

Default headers applied to every request.

timeout_ms: u64

Request timeout in milliseconds.

max_redirects: u8

Maximum number of redirects to follow.

Implementations

impl HttpClient

pub fn new() -> Self

Create a new HTTP client with default settings.

pub fn set_default_header(&mut self, name: &str, value: &str)

Set a default header that will be applied to every request.

pub fn prepare_request(&self, request: &mut HttpRequest) -> Vec<u8>

Prepare a request: apply default headers and serialize to bytes.

pub fn create_parser(&self) -> ResponseParser

Create a new response parser for receiving response data.

pub fn get(&self, url: &str) -> Result<Vec<u8>, HttpError>

Convenience: build and serialize a GET request.

pub fn post( &self, url: &str, body: &[u8], content_type: &str, ) -> Result<Vec<u8>, HttpError>

Convenience: build and serialize a POST request with a body.

pub fn follow_redirect( &self, response: &HttpResponse, original_url: &str, remaining_redirects: &mut u8, ) -> Result<Option<HttpRequest>, HttpError>

Process a redirect response: returns a new request to the redirect location, or None if not a redirect. Decrements remaining_redirects.
