Variants

Invalid

Invalid expression, e.g. syntax error

Null

null

Boolean(bool)

Boolean (true or false)

Text(String)

Text, e.g “Hello, world!”

Decimal(Decimal)

Decimal, e.g 123.456789123456

Integer(Integer)

Integer, e.g 123456789123456789

Endpoint(Endpoint)

Endpoint, e.g. @test_a or @test_b

Array(Vec<DatexExpression>)

Array, e.g [1, 2, 3, "text"]

Object(Vec<(DatexExpression, DatexExpression)>)

Object, e.g {“key”: “value”, key2: 2}

Tuple(Vec<TupleEntry>)

Tuple, e.g (1: 2, 3: 4, “xy”) or without brackets: 1,2,a:3

Statements(Vec<Statement>)

One or more statements, e.g (1; 2; 3)

Variable(Option<VariableId>, String)

Identifier, e.g. a variable name. VariableId is always set to 0 by the ast parser.

VariableDeclaration(Option<VariableId>, VariableType, VariableMutType, String, Box<DatexExpression>)

Variable declaration, e.g. const x = 1, const mut x = 1, or var y = 2. VariableId is always set to 0 by the ast parser.

VariableAssignment(Option<VariableId>, String, Box<DatexExpression>)

Variable assignment, e.g. x = 1. VariableId is always set to 0 by the ast parser.

Slot(Slot)

Slot, e.g. #1, #endpoint

SlotAssignment(Slot, Box<DatexExpression>)

Slot assignment

BinaryOperation(BinaryOperator, Box<DatexExpression>, Box<DatexExpression>)

UnaryOperation(UnaryOperator, Box<DatexExpression>)

ApplyChain(Box<DatexExpression>, Vec<Apply>)

Placeholder

RemoteExecution(Box<DatexExpression>, Box<DatexExpression>)

Trait Implementations

impl Clone for DatexExpression

fn clone(&self) -> DatexExpression

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for DatexExpression

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

Formats the value using the given formatter.

impl PartialEq for DatexExpression

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

impl TryFrom<DatexExpression> for ValueContainer

type Error = ()

The type returned in the event of a conversion error.

fn try_from(expr: DatexExpression) -> Result<Self, Self::Error>

Performs the conversion.

impl StructuralPartialEq for DatexExpression
