Struct SslMode

pub struct SslMode(/* private fields */);

Options controlling the behavior of an SslContext.

Implementations

impl SslMode

pub const ENABLE_PARTIAL_WRITE: SslMode = _

Enables “short writes”.

Normally, a write in OpenSSL will always write out all of the requested data, even if it requires more than one TLS record or write to the underlying stream. This option will cause a write to return after writing a single TLS record instead.

pub const ACCEPT_MOVING_WRITE_BUFFER: SslMode = _

Disables a check that the data buffer has not moved between calls when operating in a nonblocking context.

pub const AUTO_RETRY: SslMode = _

Enables automatic retries after TLS session events such as renegotiations or heartbeats.

By default, OpenSSL will return a WantRead error after a renegotiation or heartbeat. This option will cause OpenSSL to automatically continue processing the requested operation instead.

Note that SslStream::read and SslStream::write will automatically retry regardless of the state of this option. It only affects SslStream::ssl_read and SslStream::ssl_write.

pub const NO_AUTO_CHAIN: SslMode = _

Disables automatic chain building when verifying a peer’s certificate.

TLS peers are responsible for sending the entire certificate chain from the leaf to a trusted root, but some will incorrectly not do so. OpenSSL will try to build the chain out of certificates it knows of, and this option will disable that behavior.

pub const RELEASE_BUFFERS: SslMode = _

Release memory buffers when the session does not need them.

This saves ~34 KiB of memory for idle streams.

pub const SEND_FALLBACK_SCSV: SslMode = _

Sends the fake TLS_FALLBACK_SCSV cipher suite in the ClientHello message of a handshake.

This should only be enabled if a client has failed to connect to a server which attempted to downgrade the protocol version of the session.

Do not use this unless you know what you’re doing!

The bitwise or (|) of the bits in two flags values.

pub fn remove(&mut self, other: SslMode)

The intersection of a source flags value with the complement of a target flags value (&!).

This method is not equivalent to self & !other when other has unknown bits set. remove won’t truncate other, but the ! operator will.

The bitwise exclusive-or (^) of the bits in two flags values.

pub fn set(&mut self, other: SslMode, value: bool)

The bitwise exclusive-or (^) of the bits in two flags values.

pub const fn complement(self) -> SslMode

The bitwise negation (!) of the bits in a flags value, truncating the result.

impl SslMode

pub const fn iter(&self) -> Iter<SslMode>

Yield a set of contained flags values.

Each yielded flags value will correspond to a defined named flag. Any unknown bits will be yielded together as a final flags value.

pub const fn iter_names(&self) -> IterNames<SslMode>

Yield a set of contained named flags values.

This method is like iter, except only yields bits in contained named flags. Any unknown bits, or bits not corresponding to a contained flag will not be yielded.
