Crate s3s_http3 

Experimental server-side HTTP/3 transport for s3s.

This crate adapts an existing s3s::service::S3Service to a configured Quinn QUIC endpoint. Request and response bodies are streamed without buffering objects in the adapter.

TLS and networking

The supplied Endpoint must use QUIC TLS 1.3 with the h3 ALPN protocol. Certificate management is intentionally left to the caller. The endpoint must be reachable over UDP, including through firewalls, load balancers, and NAT configuration.

Client compatibility

Clients must support HTTP/3 over QUIC. This crate is server-side only and does not provide HTTP/3 clients, 0-RTT, datagrams, or WebTransport.

Stability

The API is experimental and may change while the HTTP/3 ecosystem evolves. HTTP/3 remains opt-in; existing s3s services and binaries are unaffected.

Structs

A QUIC endpoint.

Constants

DEFAULT_SHUTDOWN_TIMEOUT

Maximum time allowed for HTTP/3 connections to drain and close during shutdown.

Functions
