An expression, mostly useful for getting values

Variants

Parentheses

A statement in parentheses, such as (#list)

Fields of Parentheses

contained: ContainedSpan<'a>

The parentheses of the ParenExpression

expression: Box<Expression<'a>>

The expression inside the parentheses

UnaryOperator

A unary operation, such as #list

Fields of UnaryOperator

unop: UnOp<'a>

The unary operation, the # part of #list

expression: Box<Expression<'a>>

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

Value

A value, such as "strings"

Fields of Value

value: Box<Value<'a>>

The value itself

binop: Option<BinOpRhs<'a>>

The binary operation being done, if one exists (the + 3 part of 2 + 3)

Trait Implementations

impl<'a> Clone for Expression<'a>

fn clone(&self) -> Expression<'a>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<'a> Debug for Expression<'a>

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

Formats the value using the given formatter.

impl<'de: 'a, 'a> Deserialize<'de> for Expression<'a>

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

Deserialize this value from the given Serde deserializer.

impl<'a> Display for Expression<'a>

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

Formats the value using the given formatter.

impl<'a> Node<'a> for Expression<'a>

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<'b>(&'b self) -> Tokens<'a, 'b>ⓘ

Important traits for Tokens<'ast, 'b>

impl<'ast, 'b> Iterator for Tokens<'ast, 'b> type Item = Cow<'b, TokenReference<'ast>>;

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<'b>(
    &'b self
) -> (Vec<Cow<'b, Token<'ast>>>, Vec<Cow<'b, Token<'ast>>>)

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<'a> Owned for Expression<'a>

type Owned = Expression<'static>

What an owned version of the object looks like. Usually contains a 'static lifetime.

fn owned(&self) -> Self::Owned

Returns an owned version of the object.

impl<'a> PartialEq<Expression<'a>> for Expression<'a>

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

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

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

This method tests for !=.

impl<'a> Serialize for Expression<'a>

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