Variants§

§

Number(f64)

A number is a floating-point value.

§

Bool(bool)

A boolean value is either true or false.

§

Null

A null value represents the absence of a value.

§

List(ListPointer)

A list is a sequence of values.

§

String(StringPointer)

A string is a sequence of characters.

§

Record(RecordPointer)

A record is a collection of key-value pairs.

§

Lambda(LambdaPointer)

A lambda is a function definition.

§

Spread(IterablePointer)

A spread value is “spread” into its container when it is used in a list, record, or function call. (internal only)

§
