An expression, mostly useful for getting values

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

BinaryOperator

Fields

lhs: Box<Expression>

The left hand side of the binary operation, the 1 part of 1 + 3

binop: BinOp

The binary operation used, the + part of 1 + 3

rhs: Box<Expression>

The right hand side of the binary operation, the 3 part of 1 + 3

A binary operation, such as 1 + 3

Parentheses

Fields

contained: ContainedSpan

The parentheses of the ParenExpression

expression: Box<Expression>

The expression inside the parentheses

A statement in parentheses, such as (#list)

UnaryOperator

Fields

unop: UnOp

The unary operation, the # part of #list

expression: Box<Expression>

The expression the operation is being done on, the list part of #list

A unary operation, such as #list

Value

Fields

value: Box<Value>

The value itself

type_assertion: Option<TypeAssertion>

What the value is being asserted as using ::. Only available when the “roblox” feature flag is enabled.

A value, such as “strings”

Trait Implementations

impl Clone for Expression

fn clone(&self) -> Expression

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Expression

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Expression

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error> where
    __D: Deserializer<'de>, 

Deserialize this value from the given Serde deserializer.

impl Display for Expression

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

Formats the value using the given formatter.

impl Node for Expression

fn start_position(&self) -> Option<Position>

The start position of a node. None if can’t be determined

fn end_position(&self) -> Option<Position>

The end position of a node. None if it can’t be determined

fn similar(&self, other: &Self) -> bool

Whether another node of the same type is the same as this one semantically, ignoring position

fn tokens<'a>(&'a self) -> Tokens<'a>

The token references that comprise a node

fn range(&self) -> Option<(Position, Position)>

The full range of a node, if it has both start and end positions

fn surrounding_trivia(&self) -> (Vec<&Token>, Vec<&Token>)

The tokens surrounding a node that are ignored and not accessible through the node’s own accessors. Use this if you want to get surrounding comments or whitespace. Returns a tuple of the leading and trailing trivia.

impl PartialEq<Expression> for Expression

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

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

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

This method tests for !=.

impl Serialize for Expression

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

Serialize this value into the given Serde serializer.

impl StructuralPartialEq for Expression
