Expand description

Options controlling the behavior of an SslContext.

Implementations§

source§

impl SslMode

source

pub const ENABLE_PARTIAL_WRITE: Self = _

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.

source

pub const ACCEPT_MOVING_WRITE_BUFFER: Self = _

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

source

pub const AUTO_RETRY: Self = _

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.

source

pub const NO_AUTO_CHAIN: Self = _

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.

source

pub const RELEASE_BUFFERS: Self = _

Release memory buffers when the session does not need them.

This saves ~34 KiB of memory for idle streams.

source

pub const SEND_FALLBACK_SCSV: Self = _

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!

source§

impl SslMode

source

pub const fn empty() -> Self

Get a flags value with all bits unset.

source

pub const fn all() -> Self

Get a flags value with all known bits set.

source

pub const fn bits(&self) -> c_long

Get the underlying bits value.

The returned value is exactly the bits set in this flags value.

source

pub const fn from_bits(bits: c_long) -> Option<Self>

Convert from a bits value.

This method will return None if any unknown bits are set.

source

pub const fn from_bits_truncate(bits: c_long) -> Self

Convert from a bits value, unsetting any unknown bits.

source

pub const fn from_bits_retain(bits: c_long) -> Self

Convert from a bits value exactly.

source

pub fn from_name(name: &str) -> Option<Self>

Get a flags value with the bits of a flag with the given name set.

This method will return None if name is empty or doesn’t correspond to any named flag.

source

pub const fn is_empty(&self) -> bool

Whether all bits in this flags value are unset.

source

pub const fn is_all(&self) -> bool

Whether all known bits in this flags value are set.

source

pub const fn intersects(&self, other: Self) -> bool

Whether any set bits in a source flags value are also set in a target flags value.

source

pub const fn contains(&self, other: Self) -> bool

Whether all set bits in a source flags value are also set in a target flags value.

source

pub fn insert(&mut self, other: Self)

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

source

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

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.

source

pub fn toggle(&mut self, other: Self)

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

source

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

Call insert when value is true or remove when value is false.

source

pub const fn intersection(self, other: Self) -> Self

The bitwise and (&) of the bits in two flags values.

source

pub const fn union(self, other: Self) -> Self

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

source

pub const fn difference(self, other: Self) -> Self

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. difference won’t truncate other, but the ! operator will.

source

pub const fn symmetric_difference(self, other: Self) -> Self

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

source

pub const fn complement(self) -> Self

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

source§

impl SslMode

source

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.

source

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.
