Struct ServeOptions 

pub struct ServeOptions {
    pub max_concurrency: Option<usize>,
    pub max_serve_errors: Option<usize>,
    pub request_timeout_ms: Option<u64>,
    pub max_connections_per_peer: Option<usize>,
    pub max_request_body_bytes: Option<usize>,
    pub drain_timeout_ms: Option<u64>,
    pub max_total_connections: Option<usize>,
    pub load_shed: Option<bool>,
}

Options for the HTTP serve loop.

Passed directly to serve() or serve_with_events(). These govern per-request middleware (Tower layers), inbound connection caps, and serve-loop lifecycle — they do not affect outgoing fetch calls.

Fields

max_concurrency: Option<usize>

Maximum simultaneous in-flight requests. Default: 1024.

max_serve_errors: Option<usize>

Consecutive accept-loop errors before the serve loop terminates. Default: 5.

request_timeout_ms: Option<u64>

Per-request timeout in milliseconds. Default: 60 000.

max_connections_per_peer: Option<usize>

Maximum connections from a single peer. Default: 8.

max_request_body_bytes: Option<usize>

Reject request bodies larger than this many bytes. Default: 16 MiB.

drain_timeout_ms: Option<u64>

Graceful shutdown drain window in milliseconds. Default: 30 000.

max_total_connections: Option<usize>

Maximum total QUIC connections the server will accept. Default: unlimited.

load_shed: Option<bool>

When true (the default), reject new requests immediately with 503 Service Unavailable when max_concurrency is already reached rather than queuing them. Prevents thundering-herd on recovery.

Trait Implementations
