Struct rustls::ServerConfig

pub struct ServerConfig {
    pub ignore_client_order: bool,
    pub max_fragment_size: Option<usize>,
    pub session_storage: Arc<dyn StoresServerSessions + Send + Sync>,
    pub ticketer: Arc<dyn ProducesTickets>,
    pub cert_resolver: Arc<dyn ResolvesServerCert>,
    pub alpn_protocols: Vec<Vec<u8>>,
    pub key_log: Arc<dyn KeyLog>,
    // some fields omitted
}

Common configuration for a set of server sessions.

Making one of these can be expensive, and should be once per process rather than once per connection.

These must be created via the ServerConfig::builder() function.

Defaults

• ServerConfig::max_fragment_size: the default is None: TLS packets are not fragmented to a specific size.
• ServerConfig::session_storage: the default stores 256 sessions in memory.
• ServerConfig::alpn_protocols: the default is empty – no ALPN protocol is negotiated.
• ServerConfig::key_log: key material is not logged.

Fields

ignore_client_order: bool

Ignore the client’s ciphersuite order. Instead, choose the top ciphersuite in the server list which is supported by the client.

max_fragment_size: Option<usize>

The maximum size of TLS message we’ll emit. If None, we don’t limit TLS message lengths except to the 2**16 limit specified in the standard.

rustls enforces an arbitrary minimum of 32 bytes for this field. Out of range values are reported as errors from ServerConnection::new.

Setting this value to the TCP MSS may improve latency for stream-y workloads.

session_storage: Arc<dyn StoresServerSessions + Send + Sync>

How to store client sessions.

ticketer: Arc<dyn ProducesTickets>

How to produce tickets.

cert_resolver: Arc<dyn ResolvesServerCert>

How to choose a server cert and key.

alpn_protocols: Vec<Vec<u8>>

Protocol names we support, most preferred first. If empty we don’t do ALPN at all.

key_log: Arc<dyn KeyLog>

How to output key material for debugging. The default does nothing.
