An object that specifies a value for a property.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

boolean_value: Option<bool>

A Boolean value.

double_value: Option<f64>

A double value.

integer_value: Option<i32>

An integer value.

long_value: Option<i64>

A long value.

string_value: Option<String>

A string value.

list_value: Option<Vec<DataValue>>

A list of multiple values.

map_value: Option<HashMap<String, DataValue>>

An object that maps strings to multiple DataValue objects.

relationship_value: Option<RelationshipValue>

A value that relates a component to another component.

expression: Option<String>

An expression that produces the value.

Implementations

impl DataValue

pub fn boolean_value(&self) -> Option<bool>

A Boolean value.

pub fn double_value(&self) -> Option<f64>

A double value.

pub fn integer_value(&self) -> Option<i32>

An integer value.

pub fn long_value(&self) -> Option<i64>

A long value.

pub fn string_value(&self) -> Option<&str>

A string value.

pub fn list_value(&self) -> &[DataValue]

A list of multiple values.

If no value was sent for this field, a default will be set. If you want to determine if no value was sent, use .list_value.is_none().

pub fn map_value(&self) -> Option<&HashMap<String, DataValue>>

An object that maps strings to multiple DataValue objects.

pub fn relationship_value(&self) -> Option<&RelationshipValue>

A value that relates a component to another component.

pub fn expression(&self) -> Option<&str>

An expression that produces the value.

impl DataValue

pub fn builder() -> DataValueBuilder

Creates a new builder-style object to manufacture DataValue.

Trait Implementations

impl Clone for DataValue

fn clone(&self) -> DataValue

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for DataValue

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

Formats the value using the given formatter.

impl PartialEq for DataValue

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