Implementations

impl Variable

pub fn new<S: Into<String>>(name: S) -> Self

Trait Implementations

impl Clone for Variable

fn clone(&self) -> Variable

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Variable

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

Formats the value using the given formatter.

impl From<FieldExpression> for Variable

fn from(field: FieldExpression) -> Self

Converts to this type from the input type.

impl From<Identifier> for Variable

fn from(identifier: Identifier) -> Self

Converts to this type from the input type.

impl From<IndexExpression> for Variable

fn from(index: IndexExpression) -> Self

Converts to this type from the input type.

impl From<Variable> for Expression

fn from(variable: Variable) -> Self

Converts to this type from the input type.

impl PartialEq for Variable

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