Parameters

Parameters in function definitions describes how data values are passed to the function logic. Every parameter type has an associated value type, although this data handling is simplified for function implementations over other provider concepts, such as resource implementations.

Available Parameter Types

Function definitions support the following parameter types:

Primitive: Parameter that accepts a single value, such as a boolean, number, or string.
Collection: Parameter that accepts multiple values of a single element type, such as a list, map, or set.
Object: Parameter that accepts a structure of explicit attribute names.

Primitive Parameter Types

Parameter types that accepts a single data value, such as a boolean, number, or string.

Parameter Type	Use Case
Bool	Boolean true or false
Float64	64-bit floating point number
Int64	64-bit integer number
Number	Arbitrary precision (generally over 64-bit, up to 512-bit) number
String	Collection of UTF-8 encoded characters

Collection Parameter Types

Parameter types that accepts multiple values of a single element type, such as a list, map, or set.

Parameter Type	Use Case
List	Ordered collection of single element type
Map	Mapping of arbitrary string keys to values of single element type
Set	Unordered, unique collection of single element type

Object Parameter Type

Parameter type that accepts a structure of explicit attribute names.

Parameter Type	Use Case
Object	Single structure mapping explicit attribute names
