Struct BitmaskOperator 

pub struct BitmaskOperator {
    pub end_of_list: bool,
    pub and_with_next: bool,
    pub value_length: u8,
    pub not: bool,
    pub match_flag: bool,
    pub bitmask: u64,
}

Bitmask operator for Flow-Spec components (RFC 8955 Section 4.2.2)

Fields

end_of_list: bool

End-of-list flag (bit 7)

and_with_next: bool

AND flag - true=AND with next, false=OR with next (bit 6)

value_length: u8

Value length in octets (bits 5-4): 00=1, 01=2, 10=4, 11=8

not: bool

NOT flag - logical negation (bit 1)

match_flag: bool

Match flag - true=partial match, false=exact match (bit 0)

bitmask: u64

The bitmask value

Implementations

impl BitmaskOperator

pub fn from_byte_and_value( operator_byte: u8, bitmask: u64, ) -> Result<Self, FlowSpecError>

Create a new bitmask operator from raw byte and value

pub fn to_byte(&self) -> u8

Convert to byte representation

pub fn exact_match(bitmask: u64) -> Self

Create exact match operator

pub fn partial_match(bitmask: u64) -> Self

Create partial match operator

Trait Implementations

impl Clone for BitmaskOperator

fn clone(&self) -> BitmaskOperator

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for BitmaskOperator

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

Formats the value using the given formatter.

impl PartialEq for BitmaskOperator

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