Struct H2Connection 

pub struct H2Connection { /* private fields */ }

The HTTP/2 connection handle. Cheap to clone (shares one Rc state).

Implementations

impl H2Connection

pub fn is_closed(&self) -> bool

True once the connection has been torn down.

pub fn active_streams(&self) -> usize

Client-initiated streams currently open or half-closed — the ones that count toward the peer’s SETTINGS_MAX_CONCURRENT_STREAMS (§5.1.2).

pub fn can_open_stream(&self) -> bool

True if a new request would stay within the peer’s advertised SETTINGS_MAX_CONCURRENT_STREAMS. A connection pool uses this to decide whether to route here or open a fresh connection; a direct caller need not check — request parks until a slot frees.

pub async fn request(&self, init: RequestInit) -> Result<Response, H2Error>

The negotiated WebSocket subprotocol, if opened via a WebSocket (set by the caller). Empty otherwise.

pub async fn ping(&self) -> Result<f64, H2Error>

Send a PING and resolve with the round-trip time in milliseconds.

pub fn close(&self)

Gracefully close: send GOAWAY, then tear down.
