Struct Client 

pub struct Client {
    pub cookie_store: Arc<RwLock<CookieStore>>,
    pub hint_cache: Arc<RwLock<HashSet<String>>>,
    pub alt_svc_cache: AltSvcCache,
    pub tls_session_cache: Arc<Mutex<HashMap<String, SslSession>>>,
    /* private fields */
}

A stateful HTTP client engine enforcing deterministic Chrome identity parity.

The Client is the primary interface for managing cross-origin requests. It maintains global state across its clones, enabling shared connection pooling and cookie persistence. Key operational guarantees include:

• Transport Decoupling: Transparently routes requests over H2 or H3 based on cache states.
• Connection Pooling: Reuses established multiplexed streams isolated by proxy and origin.
• Automated State Tracking: Synchronizes cookies, redirects, and client-hints seamlessly.

Fields

cookie_store: Arc<RwLock<CookieStore>>

A synchronized cookie jar enforcing RFC 6265 storage and cross-request persistence.

hint_cache: Arc<RwLock<HashSet<String>>>

A cache tracking origins that explicitly solicited dynamic client hints (e.g. Accept-CH).

alt_svc_cache: AltSvcCache

Thread-safe registry mapping origins to discovered Alt-Svc UDP/QUIC endpoints.

tls_session_cache: Arc<Mutex<HashMap<String, SslSession>>>

A synchronized cache of TLS sessions for resumption, keyed by origin/host.

Implementations

impl Client

pub fn new() -> Self

Creates a new Client with a Chrome profile auto-matched to the host OS.

By default, this constructor initializes a ClientBuilder and compiles the default profile to the active host platform (e.g. chrome_148 on Linux/macOS/Windows). If builder initialization fails, it statefully falls back to the static chrome_148 auto-profile to guarantee uninterrupted transport-level compliance.

pub fn builder() -> ClientBuilder

Returns a ClientBuilder to configure a specialized Client instance.

pub async fn get(&self, url: &str) -> Result<Response>

Executes a GET request and follows redirects stealthily.

pub async fn post(&self, url: &str, body: Bytes) -> Result<Response>

Executes a POST request and follows redirects stealthily.

Trait Implementations

impl Clone for Client

fn clone(&self) -> Client

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Default for Client

fn default() -> Self

Returns the “default value” for a type.
