Struct Expression

pub struct Expression<'a, I: SemanticContextInstruction, E: ExtendedExpression<I>> {
    pub expression_value: ExpressionValue<'a, I, E>,
    pub operation: Option<(ExpressionOperations, Box<Expression<'a, I, E>>)>,
}

Expression element of AST is basic entity that represent expression, and optionally expression with optional operations with other expression. So it can be expression tree with expression operations.

Fields

expression_value: ExpressionValue<'a, I, E>

Expression value itself

operation: Option<(ExpressionOperations, Box<Expression<'a, I, E>>)>

Optional expression operation with other expression value

Trait Implementations

impl<'a, I: Clone + SemanticContextInstruction, E: Clone + ExtendedExpression<I>> Clone for Expression<'a, I, E>

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

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<'a, I: Debug + SemanticContextInstruction, E: Debug + ExtendedExpression<I>> Debug for Expression<'a, I, E>

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

fn location(&self) -> CodeLocation

impl<'a, I: PartialEq + SemanticContextInstruction, E: PartialEq + ExtendedExpression<I>> PartialEq for Expression<'a, I, E>

fn eq(&self, other: &Expression<'a, I, E>) -> 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.
