Struct TcpIndexKey 

pub struct TcpIndexKey {
    pub ip_version_key: IpVersion,
    pub olayout_key: String,
    pub pclass_key: PayloadSize,
}

Index key for TCP signatures, used to optimize database lookups.

This key is generated from a tcp::Signature and combines several of its most discriminative fields to allow for a fast initial filtering of potential matches in the signature database. The goal is to quickly narrow down the search space before performing more detailed and costly distance calculations.

The fields included are chosen for their balance of providing good discrimination while not being overly specific to avoid missing matches due to minor variations (which are handled by the distance calculation).

Fields

ip_version_key: IpVersion

olayout_key: String

pclass_key: PayloadSize

Trait Implementations

impl Clone for TcpIndexKey

fn clone(&self) -> TcpIndexKey

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for TcpIndexKey

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

Formats the value using the given formatter.

impl Hash for TcpIndexKey

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 PartialEq for TcpIndexKey

fn eq(&self, other: &TcpIndexKey) -> 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.
