Enum ConditionExpression

pub(crate) enum ConditionExpression {
    Condition(Condition),
    Expr(Expr),
}

An internal representation of conditions. May be refactored away in the future if we can get our head around it.

It used to be in the public interface of Condition::add and Condition::add_option, in order to accept anything resembling a condition or an expression. Nowadays, we achieve that with traits.

Variants

Condition(Condition)

Expr(Expr)

Trait Implementations

impl Clone for ConditionExpression

fn clone(&self) -> ConditionExpression

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ConditionExpression

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

Formats the value using the given formatter.

impl From<Condition> for ConditionExpression

fn from(condition: Condition) -> Self

Converts to this type from the input type.

impl From<ConditionExpression> for Condition

fn from(ce: ConditionExpression) -> Self

Converts to this type from the input type.

impl From<ConditionExpression> for Expr

fn from(ce: ConditionExpression) -> Self

Converts to this type from the input type.

impl From<Expr> for ConditionExpression

fn from(condition: Expr) -> Self

Converts to this type from the input type.

impl PartialEq for ConditionExpression

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