Struct KeyValue 

pub struct KeyValue {
    pub key: Rc<str>,
    pub value: Expression,
    pub guard: Option<Expression>,
}

An entry of a dictionary expression.

Fields

key: Rc<str>

The string value associated with the Ryan value.

value: Expression

The expression that evaluates to the value of this association.

guard: Option<Expression>

An optional if guard. If the supplied expression evaluates to false, the current key-value pair is not inserted in the final dictionary.

Trait Implementations

impl Clone for KeyValue

fn clone(&self) -> KeyValue

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for KeyValue

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

Formats the value using the given formatter.

impl Display for KeyValue

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

Formats the value using the given formatter.

impl PartialEq for KeyValue

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