Overview

Package function contains all interfaces, request types, and response types for a Terraform Provider function implementation.

In Terraform, a function is a concept which enables provider developers to offer practitioners a pure function call in their configuration. Functions are defined by a function name, such as "parse_xyz", a definition representing the ordered list of parameters with associated data types and a result data type, and the function logic.

The main starting point for implementations in this package is the Function type which represents an instance of a function that has its own argument data when called. The Function implementations are referenced by a [provider.Provider] type Functions method, which enables the function for practitioner and testing usage.

Practitioner feedback is provided by the FuncError type, rather than the diag.Diagnostic type.

Types

type ArgumentsData 

type ArgumentsData struct {
	// contains filtered or unexported fields
}

ArgumentsData is the zero-based positional argument data sent by Terraform for a single function call. Use the Get method or GetArgument method in the Function type Run method to fetch the data.

This data is automatically populated by the framework based on the function definition. For unit testing, use the NewArgumentsData function to manually create the data.

func NewArgumentsData 

func NewArgumentsData(values []attr.Value) ArgumentsData

NewArgumentsData creates an ArgumentsData. This is only necessary for unit testing as the framework automatically creates this data.

func (ArgumentsData) Equal 

func (d ArgumentsData) Equal(o ArgumentsData) bool

Equal returns true if all the underlying values are equivalent.

func (ArgumentsData) Get 

func (d ArgumentsData) Get(ctx context.Context, targets ...any) *FuncError

Get retrieves all argument data and populates the targets with the values. All arguments must be present in the targets, including all parameters and an optional variadic parameter, otherwise an error diagnostic will be raised. Each target type must be acceptable for the data type in the parameter definition.

Variadic parameter argument data must be consumed by a types.Tuple or Go slice type with an element type appropriate for the parameter definition ([]T). The framework automatically populates this tuple with elements matching the zero, one, or more arguments passed.

func (ArgumentsData) GetArgument 

func (d ArgumentsData) GetArgument(ctx context.Context, position int, target any) *FuncError

GetArgument retrieves the argument data found at the given zero-based position and populates the target with the value. The target type must be acceptable for the data type in the parameter definition.

Variadic parameter argument data must be consumed by a types.Tuple or Go slice type with an element type appropriate for the parameter definition ([]T) at the position after all parameters. The framework automatically populates this tuple with elements matching the zero, one, or more arguments passed.

type BoolParameter 

type BoolParameter struct {
	// AllowNullValue when enabled denotes that a null argument value can be
	// passed to the function. When disabled, Terraform returns an error if the
	// argument value is null.

	AllowUnknownValues bool

	// CustomType enables the use of a custom data type in place of the

	// position the parameter is in the function definition. ("param1", "param2", etc.)
	// If the parameter is variadic, the default name will be "varparam".
	//
	// This must be a valid Terraform identifier, such as starting with an
	// alphabetical character and followed by alphanumeric or underscore
	// characters.

	// ValidateParameterString performs the validation.
	ValidateParameterString(context.Context, StringParameterValidatorRequest, *StringParameterValidatorResponse)
}

StringParameterValidator is a function validator for types.String parameters.

type StringParameterValidatorRequest added in v1.8.0 

type StringParameterValidatorRequest struct {
	// ArgumentPosition contains the position of the argument for validation.
	// Use this position for any response diagnostics.
	ArgumentPosition int64

	// Value contains the value of the argument for validation.
	Value types.String
}

StringParameterValidatorRequest is a request for types.String schema validation.

type StringParameterValidatorResponse added in v1.8.0 

type StringParameterValidatorResponse struct {
	// Error is a function error generated during validation of the Value.
	Error *FuncError
}

StringParameterValidatorResponse is a response to a StringParameterValidatorRequest.

type StringReturn 

type StringReturn struct {
	// CustomType enables the use of a custom data type in place of the
	// default [basetypes.StringType]. When setting data, the
	// [basetypes.StringValuable] implementation associated with this custom
	// type must be used in place of [types.String].
	CustomType basetypes.StringTypable
}

StringReturn represents a function return that is a string.

When setting the value for this return:

- If CustomType is set, use its associated value type. - Otherwise, use types.String, *string, or string.

Return documentation is expected in the function Definition documentation.

func (StringReturn) GetType 

func (r StringReturn) GetType() attr.Type

GetType returns the return data type.

func (StringReturn) NewResultData 

func (r StringReturn) NewResultData(ctx context.Context) (ResultData, *FuncError)

NewResultData returns a new result data based on the type.

type ValidateParameterRequest added in v1.8.0 

type ValidateParameterRequest struct {
	// Position is the zero-ordered position of the parameter being validated.
	Position int64
}

ValidateParameterRequest represents a request for the attr.Value to call its validation logic. An instance of this request struct is supplied as an argument to the attr.Value type ValidateParameter method.

type ValidateParameterResponse added in v1.8.0 

type ValidateParameterResponse struct {
	// Error is a function error generated during validation of the attr.Value.
	Error *FuncError
}

ValidateParameterResponse represents a response to a ValidateParameterRequest. An instance of this response struct is supplied as an argument to the ValidateParameter method.

type ValidateableParameter added in v1.8.0 

type ValidateableParameter interface {
	// ValidateParameter returns any error generated during validation
	// of the parameter. It is generally used to check the data format and ensure
	// that it complies with the requirements of the attr.Value.
	ValidateParameter(context.Context, ValidateParameterRequest, *ValidateParameterResponse)
}

ValidateableParameter defines an interface for validating a parameter value.
