Enum BooleanExpr 

pub enum BooleanExpr {
    Or(Box<BooleanExpr>, Box<BooleanExpr>),
    And(Box<BooleanExpr>, Box<BooleanExpr>),
    Not(Box<BooleanExpr>),
    Literal(bool),
    Variable(String),
    Relational(RelationalExpr),
}

Root expression type - must evaluate to boolean

Variants

Or(Box<BooleanExpr>, Box<BooleanExpr>)

Logical OR operation (lowest precedence)

And(Box<BooleanExpr>, Box<BooleanExpr>)

Logical AND operation

Not(Box<BooleanExpr>)

Logical NOT operation

Literal(bool)

Boolean literal (TRUE or FALSE)

Variable(String)

Variable reference (type checked at runtime)

Relational(RelationalExpr)

Relational expression (comparisons that produce boolean results)

Trait Implementations

impl Clone for BooleanExpr

fn clone(&self) -> BooleanExpr

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for BooleanExpr

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

Formats the value using the given formatter.

impl Display for BooleanExpr

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

Formats the value using the given formatter.

impl PartialEq for BooleanExpr

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