Struct Expression

pub struct Expression {
    pub expression_value: ExpressionValue,
    pub operation: Option<(ExpressionOperations, Box<Expression>)>,
}

Expression

Basic expression entity representation. It contains ExpressionValue and optional operations with other expressions. So it’s represent flat tree.

Fields

expression_value: ExpressionValue

Expression value

operation: Option<(ExpressionOperations, Box<Expression>)>

Optional expression operation under other Expression

Trait Implementations

impl Clone for Expression

fn clone(&self) -> Expression

Returns a duplicate 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 Display for Expression

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

Formats the value using the given formatter.

impl<I: SemanticContextInstruction, E: ExtendedExpression<I>> From<Expression<'_, I, E>> for Expression

fn from(value: Expression<'_, I, E>) -> Self

Converts to this type from the input type.

impl PartialEq for Expression

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