Struct VariableCharacteristics

    pub custom_data: Option<CustomDataType>,

Fixed read-only parameters of a variable.

Fields

custom_data: Option<CustomDataType>

data_type: DataEnum

max_elements: Option<i64>

(2.1) Maximum number of elements from valuesList that are supported as attributeValue.

max_limit: Option<f64>

Maximum possible value of this variable. When the datatype of this Variable is String, OptionList, SequenceList or MemberList, this field defines the maximum length of the (CSV) string.

min_limit: Option<f64>

Minimum possible value of this variable.

supports_monitoring: bool

Flag indicating if this variable supports monitoring.

unit: Option<String<16usize>>

Unit of the variable. When the transmitted value has a unit, this field SHALL be included.

values_list: Option<String>

Mandatory when dataType = OptionList, MemberList or SequenceList. In that case valuesList specifies the allowed values for the type.

The length of this field can be limited by DeviceDataCtrlr.ConfigurationValueSize.

• OptionList: The (Actual) Variable value must be a single value from the reported (CSV) enumeration list.

• MemberList: The (Actual) Variable value may be an (unordered) (sub-)set of the reported (CSV) valid values list.

• SequenceList: The (Actual) Variable value may be an ordered (priority, etc) (sub-)set of the reported (CSV) valid values.

This is a comma separated list.

The Configuration Variable <<configkey-configuration-value-size,ConfigurationValueSize>> can be used to limit SetVariableData.attributeValue and VariableCharacteristics.valuesList. The max size of these values will always remain equal.

Trait Implementations

impl<CustomDataType: Clone> Clone for VariableCharacteristics<CustomDataType>

fn clone(&self) -> VariableCharacteristics<CustomDataType>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<CustomDataType: Debug> Debug for VariableCharacteristics<CustomDataType>

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

Formats the value using the given formatter.

impl<'de, CustomDataType> Deserialize<'de> for VariableCharacteristics<CustomDataType>

where CustomDataType: Deserialize<'de>,

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl<CustomDataType: PartialEq> PartialEq for VariableCharacteristics<CustomDataType>

fn eq(&self, other: &VariableCharacteristics<CustomDataType>) -> bool

Equality operator ==.

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

Inequality operator !=.

impl<CustomDataType> Serialize for VariableCharacteristics<CustomDataType>

where CustomDataType: Serialize,

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl<CustomDataType: PartialEq> StructuralPartialEq for VariableCharacteristics<CustomDataType>

impl<CustomDataType> Validate for VariableCharacteristics<CustomDataType>

Available on crate features alloc and validate only.

fn validate(&self) -> Result<(), ValidationError>

Ok(()) if every schema constraint reachable from self holds, or the first violation found. Field order within a struct is the schema’s, but which violation comes first is not otherwise a stable part of the API.
