Struct QosPolicyMask 

pub struct QosPolicyMask(pub u32);

Bitmask of QoS policies a backend can honour. See Session::supported_qos_policies.

CORE covers the policies every nano-ros backend implements: reliability, durability=VOLATILE, history, depth. Backends opt into additional policies by OR-ing the relevant flags.

Trait Implementations

impl BitOr for QosPolicyMask

type Output = QosPolicyMask

The resulting type after applying the | operator.

fn bitor(self, rhs: Self) -> Self

Performs the | operation.

impl BitOrAssign for QosPolicyMask

fn bitor_assign(&mut self, rhs: Self)

Performs the |= operation.

impl Clone for QosPolicyMask

fn clone(&self) -> QosPolicyMask

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for QosPolicyMask

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

Formats the value using the given formatter.

impl PartialEq for QosPolicyMask

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