Struct QRV

pub struct QRV(/* private fields */);

QRV (Querier’s Robustness Variable) used in IGMPv3/MLDv2 messages, defined in RFC 3376 section 4.1.6 and RFC 3810 section 5.1.8.

Implementations

impl QRV

pub fn new(robustness_value: u8) -> Self

Returns the Querier’s Robustness Variable.

From RFC 3376 section 4.1.6: If the querier’s [Robustness Variable] exceeds 7, the maximum value of the QRV field, the QRV is set to zero.

From RFC 3810 section 5.1.8: If the Querier’s [Robustness Variable] exceeds 7 (the maximum value of the QRV field), the QRV field is set to zero.

Trait Implementations

impl Clone for QRV

fn clone(&self) -> QRV

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for QRV

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

Formats the value using the given formatter.

impl Default for QRV

fn default() -> QRV

Returns the “default value” for a type.

impl From<QRV> for u8

fn from(qrv: QRV) -> u8

Converts to this type from the input type.

impl PartialEq for QRV

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