Struct ConstantExpression

pub struct ConstantExpression<'a> {
    pub value: ConstantValue<'a>,
    pub operation: Option<(ExpressionOperations, Box<ConstantExpression<'a>>)>,
}

ConstantExpression constant expression element of AST. Used to declare constants. The constant expression value based on other constant or primitive values. Constant Expression can contain optional expression operation with other constant expression. So it can be represented as Constant expression tree as operations with other constant expressions.

Fields

value: ConstantValue<'a>

Constant value - can be other constant 0r primitive value

operation: Option<(ExpressionOperations, Box<ConstantExpression<'a>>)>

Constant expression optional expression operation with other constant expression declarations.

Trait Implementations

impl<'a> Clone for ConstantExpression<'a>

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

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<'a> Debug for ConstantExpression<'a>

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

Formats the value using the given formatter.

impl From<ConstantExpression<'_>> for ConstantExpression

fn from(value: ConstantExpression<'_>) -> Self

Converts to this type from the input type.

impl<'a> PartialEq for ConstantExpression<'a>

fn eq(&self, other: &ConstantExpression<'a>) -> 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.
