[−]Struct openssl::ssl::SslMode
Options controlling the behavior of an SslContext
.
Methods
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!
pub const fn empty() -> SslMode
Returns an empty set of flags
pub const fn all() -> SslMode
Returns the set containing all flags.
pub const fn bits(&self) -> c_long
Returns the raw value of the flags currently stored.
pub fn from_bits(bits: c_long) -> Option<SslMode>
Convert from underlying bit representation, unless that representation contains bits that do not correspond to a flag.
pub const fn from_bits_truncate(bits: c_long) -> SslMode
Convert from underlying bit representation, dropping any bits that do not correspond to flags.
pub const unsafe fn from_bits_unchecked(bits: c_long) -> SslMode
Convert from underlying bit representation, preserving all bits (even those not corresponding to a defined flag).
pub const fn is_empty(&self) -> bool
Returns true
if no flags are currently stored.
pub const fn is_all(&self) -> bool
Returns true
if all flags are currently set.
pub const fn intersects(&self, other: SslMode) -> bool
Returns true
if there are flags common to both self
and other
.
pub const fn contains(&self, other: SslMode) -> bool
Returns true
all of the flags in other
are contained within self
.
pub fn insert(&mut self, other: SslMode)
Inserts the specified flags in-place.
pub fn remove(&mut self, other: SslMode)
Removes the specified flags in-place.
pub fn toggle(&mut self, other: SslMode)
Toggles the specified flags in-place.
pub fn set(&mut self, other: SslMode, value: bool)
Inserts or removes the specified flags depending on the passed value.
