Enum opcua_server::prelude::MessageSecurityMode

pub enum MessageSecurityMode {
    Invalid,
    None,
    Sign,
    SignAndEncrypt,
}

The MessageSecurityMode is an enumeration that specifies what security should be applied to messages exchanges during a Session.

Variants

Invalid

The MessageSecurityMode is invalid. This value is the default value to ensure that unless explicitly set, a connection will be rejected.

None

No security is applied. This assumes a plaintext security policy.

Sign

All messages are signed but not encrypted.

SignAndEncrypt

All messages are signed and encrypted.

Trait Implementations

impl BinaryEncoder<MessageSecurityMode> for MessageSecurityMode

fn byte_len(&self) -> usize

Returns the byte length of the structure. This calculation should be exact and as efficient as possible.

fn encode<S>(&self, stream: &mut S) -> Result<usize, StatusCode> where
    S: Write, 

Encodes the instance to the write stream.

fn decode<S>(
    stream: &mut S,
    &DecodingLimits
) -> Result<MessageSecurityMode, StatusCode> where
    S: Read, 

Decodes an instance from the read stream. The decoding limits are restrictions set by the server / client on the length of strings, arrays etc. If these limits are exceeded the implementation should return with a BadDecodingError as soon as possible.

fn to_vec(&self) -> Vec<u8>

impl Clone for MessageSecurityMode

fn clone(&self) -> MessageSecurityMode

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Display for MessageSecurityMode

fn fmt(&self, f: &mut Formatter) -> Result<(), Error>

Formats the value using the given formatter.

impl Copy for MessageSecurityMode

impl<'a> From<&'a str> for MessageSecurityMode

fn from(str: &'a str) -> MessageSecurityMode

Performs the conversion.

impl PartialOrd<MessageSecurityMode> for MessageSecurityMode

fn partial_cmp(&self, other: &MessageSecurityMode) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

#[must_use]

fn lt(&self, other: &Rhs) -> bool

This method tests less than (for self and other) and is used by the < operator.

#[must_use]

fn le(&self, other: &Rhs) -> bool

This method tests less than or equal to (for self and other) and is used by the <= operator.

#[must_use]

fn gt(&self, other: &Rhs) -> bool

This method tests greater than (for self and other) and is used by the > operator.

#[must_use]

fn ge(&self, other: &Rhs) -> bool

This method tests greater than or equal to (for self and other) and is used by the >= operator.

impl PartialEq<MessageSecurityMode> for MessageSecurityMode

fn eq(&self, other: &MessageSecurityMode) -> bool

This method tests for self and other values to be equal, and is used by ==.

#[must_use]

fn ne(&self, other: &Rhs) -> bool

This method tests for !=.

impl Debug for MessageSecurityMode

fn fmt(&self, f: &mut Formatter) -> Result<(), Error>

Formats the value using the given formatter.
