Enum StateTransition 

#[repr(u8)]
pub enum StateTransition {
    L4FirstPacket = 0,
    L4EndHshk = 1,
    InL4Conn = 2,
    InL4Stream = 3,
    L7OnDisc = 4,
    L7EndHdrs = 5,
    L4Terminated = 6,
    Packet = 7,
}

The possible state transitions that a data type, filter, or callback (function and/or struct) can be associated with. Developers should refer to these in macros.

Variants

L4FirstPacket = 0

On first packet in connection

L4EndHshk = 1

Observed and reassembled SYNs and ACKs from both sides. Note that this does not validate sequence numbers of these SYNs/ACKs. Additionally, this should not be used to indicate the beginning of payload, as payload may overlap with the handshake.

InL4Conn = 2

Streaming anywhere in L4 connection, including TCP handshake. Streaming anywhere in TCP or UDP connection, including TCP handshake.

InL4Stream = 3

Streaming anywhere in TCP or UDP connection, including TCP handshake. Packets are TCP-reassembled.

L7OnDisc = 4

On L7 protocol identification

L7EndHdrs = 5

On L6/L7 headers parsed

L4Terminated = 6

L4 connection terminated by FIN/ACK sequence or timeout

Packet = 7

Packet-level datatype. Any datatype tagged with this is built from a single, connectionless packet (Mbuf).

Note: Iris currently does not support subscriptions that are not tied to a connection. Callbacks and filters should use InL4Conn to request packet-level data types.

Packet-level filters cannot be combined with datatypes or callbacks that require connection/session tracking. Packet-level datatypes can only be requested in higher-level filters/callbacks if a streaming level (e.g., InL4Conn) is specified.

Internal notes:

• This must be last in the enum variant list.
• In the connection tracker, this is used as a no-op state transition.

Trait Implementations

impl Clone for StateTransition

fn clone(&self) -> StateTransition

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for StateTransition

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for StateTransition

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for StateTransition

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

Formats the value using the given formatter.

impl Hash for StateTransition

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl IntoEnumIterator for StateTransition

type Iterator = StateTransitionIter

fn iter() -> StateTransitionIter

impl Ord for StateTransition

fn cmp(&self, other: &StateTransition) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for StateTransition

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

Tests for self and other values to be equal, and is used by ==.

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

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

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

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

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

Tests less than (for self and other) and is used by the < operator.

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

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

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

Tests greater than (for self and other) and is used by the > operator.

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

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

impl Serialize for StateTransition

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Copy for StateTransition

impl Eq for StateTransition
