Struct Config 

pub struct Config {
    pub decoder: DecoderConfig,
    pub encoder: EncoderConfig,
    pub max_requests: usize,
    pub header_read_timeout: Option<HeaderReadTimeout>,
    pub idle_timeout: Option<IdleTimeout>,
    pub max_pushes: usize,
    pub max_frame_size: usize,
    pub read_chunk_size: usize,
    pub max_pending_uni_streams: usize,
    pub extended_connect: bool,
    pub datagrams: Option<DatagramConfig>,
    pub strict_connect_framing: bool,
}

Available on crate features http-backend and http and std only.

Local HTTP/3 connection budgets. Peer limits are negotiated independently.

Fields

decoder: DecoderConfig

Local QPACK decoder limits, advertised where the protocol defines settings.

encoder: EncoderConfig

Local encoder budgets. Peer capacity/blocked-stream settings override those fields.

max_requests: usize

Maximum concurrent application requests retained by the engine.

header_read_timeout: Option<HeaderReadTimeout>

Deadline for incomplete server request heads, including blocked QPACK sections. None disables the deadline.

idle_timeout: Option<IdleTimeout>

Server connection idle budgets. None disables the deadline.

max_pushes: usize

Lifetime push quota; zero disables push. Bounds reordered push state.

max_frame_size: usize

Maximum buffered encoded non-DATA frame.

This local wire-memory budget is independent of the decoded field-section size advertised in SETTINGS. QPACK literals can expand on the wire, so exceeding this bound is excessive load even for an otherwise valid field section (RFC 9114 §10.5.1). Increase both limits for large-header peers.

read_chunk_size: usize

Maximum QUIC chunk held by a stream reader.

max_pending_uni_streams: usize

Maximum unclassified peer unidirectional streams retained simultaneously.

extended_connect: bool

Accept Extended CONNECT (RFC 9220) as a server, advertising SETTINGS_ENABLE_CONNECT_PROTOCOL. The service decides which :protocol tokens it serves; RFC 9220 §3 recommends 501 for others.

datagrams: Option<DatagramConfig>

Receive HTTP/3 datagrams (RFC 9297). When QUIC DATAGRAM is negotiated this advertises SETTINGS_H3_DATAGRAM, as RFC 9297 §2.1.1 recommends for every endpoint able to receive them; None never advertises nor delivers them. A request only has datagram semantics once declared with HttpDatagrams.

strict_connect_framing: bool

Reject, rather than drop, Content-Length or Transfer-Encoding on a successful response to CONNECT, which RFC 9110 §9.3.6 forbids as a tunnel follows the response.

Implementations

impl Config

pub fn configure_transport( &self, transport: &mut TransportConfig, ) -> Result<(), Error>

Apply finite HTTP/3 receive budgets to a QUIC transport configuration. Configure the endpoint before establishing connections.

Trait Implementations

impl Clone for Config

fn clone(&self) -> Config

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Config

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl Default for Config

fn default() -> Config

Returns the “default value” for a type.
