Struct rustdds::dds::qos::policy::ResourceLimits

pub struct ResourceLimits {
    pub max_samples: i32,
    pub max_instances: i32,
    pub max_samples_per_instance: i32,
}

DDS 2.2.3.19 RESOURCE_LIMITS DDS Spec v1.4 p.147 “struct ResourceLimitsQosPolicy” defines the fields as “long”. The “long” type of OMG IDL is defined to have 32-bit (signed, 2’s complement) range in the OMG IDL spec v4.2, Table 7-13: Integer Types.

But it does not make sense to have negative limits, so these should be unsigned.

Negative values are needed, because DDS spec defines the special value const long LENGTH_UNLIMITED = -1;

Fields

max_samples: i32

max_instances: i32

max_samples_per_instance: i32

Trait Implementations

impl Clone for ResourceLimits

fn clone(&self) -> ResourceLimits

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for ResourceLimits

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for ResourceLimits

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for ResourceLimits

fn eq(&self, other: &ResourceLimits) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
