Struct TcpFlags 

pub struct TcpFlags {
    pub mask: u8,
    pub value: u8,
}

TCP flag bitmask for matching

Fields

mask: u8

Flags that must be set

value: u8

Expected value after masking

Implementations

impl TcpFlags

pub const SYN: u8 = 2u8

pub const ACK: u8 = 16u8

pub const FIN: u8 = 1u8

pub const RST: u8 = 4u8

pub const PSH: u8 = 8u8

pub const URG: u8 = 32u8

pub const fn new(mask: u8, value: u8) -> Self

Create a new TCP flags match

pub const fn syn_only() -> Self

Match SYN-only packets (SYN set, ACK cleared)

pub const fn established() -> Self

Match established connection packets (ACK set)

pub fn matches(&self, flags: u8) -> bool

Check if the given flags match this criteria

Trait Implementations

impl Clone for TcpFlags

fn clone(&self) -> TcpFlags

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for TcpFlags

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

Formats the value using the given formatter.

impl Default for TcpFlags

fn default() -> TcpFlags

Returns the “default value” for a type.

impl PartialEq for TcpFlags

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