Available on crate feature connect and (crate features rustls-0_20-webpki-roots or rustls-0_20-native-roots) only.

Common configuration for (typically) all connections made by a program.

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

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

Defaults

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

Fields

alpn_protocols: Vec<Vec<u8>>

Which ALPN protocols we include in our client hello. If empty, no ALPN extension is sent.

session_storage: Arc<dyn StoresClientSessions>

How we store session data or tickets.

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 ClientConnection::new.

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

client_auth_cert_resolver: Arc<dyn ResolvesClientCert>

How to decide what client auth certificate/keys to use.

enable_tickets: bool

Whether to support RFC5077 tickets. You must provide a working session_storage member for this to have any meaningful effect.

The default is true.

enable_sni: bool

Whether to send the Server Name Indication (SNI) extension during the client handshake.

The default is true.

key_log: Arc<dyn KeyLog>

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

enable_early_data: bool

Whether to send data on the first flight (“early data”) in TLS 1.3 handshakes.

The default is false.
