The server configuration resolved at build time and carried by an App.

Populated from defaults, an optional Config, and the builder’s DSL setters. Read it back from a built app with App::config.

Fields

host: String

Bind address host.

port: u16

Bind port.

max_body_bytes: usize

Maximum accepted request body size in bytes; larger bodies get 413.

request_timeout_ms: u64

Per-request timeout in milliseconds; 0 disables the timeout.

header_read_timeout_ms: u64

Deadline for a client to finish sending its header block; 0 disables.

max_headers: usize

Maximum number of request headers accepted.

max_path_segments: usize

Maximum path segments before a request is rejected with 414.

ws_max_frame_bytes: usize

Maximum WebSocket frame size in bytes (ws feature).

ws_max_message_bytes: usize

Maximum reassembled WebSocket message size in bytes (ws feature).

keep_alive_ms: u64

Idle keep-alive in milliseconds; 0 disables connection reuse. Idle means no request in flight, so a slow handler is never cut off.

backlog: u32

Listen backlog.

shutdown_timeout_ms: u64

Graceful-shutdown grace period in milliseconds; 0 waits forever.

path_policy: PathPolicy

What to do with a non-canonical path spelling.

h2_max_header_list_size: u32

Maximum size of a received HTTP/2 header block, in bytes. The h2 counterpart of max_headers, which configures HTTP/1 only.

h2_max_concurrent_streams: u32

Maximum concurrent HTTP/2 streams per connection; 0 removes the limit.

ws_idle_timeout_ms: u64

WebSocket idle bound in milliseconds; 0 disables it (ws feature).

max_connections: usize

Maximum simultaneously served connections; 0 means unlimited.

max_tls_handshakes: usize

Maximum TLS handshakes in progress at once; 0 means unlimited.

tls_handshake_timeout_ms: u64

TLS handshake deadline in milliseconds; 0 disables the bound.

tls: Option<TlsSection>

TLS settings, or None for plaintext HTTP.
