Int64 Enumeration Validation (OneOf / NoneOf)

[bflad]

Terraform CLI and Framework Versions

Any Terraform CLI version; terraform-plugin-framework v0.8.0

Use Cases or Problem Statement

Provider developers should be able to generically validate types.Int64 values are part of (or not part of) a defined set of values. For example:

• Whether a known value is contained in a defined set of values
• Whether a known value is not contained in a defined set of values

Proposal

Inside a int64validator package, create two new unexported types that satisfy the tfsdk.AttributeValidator interface:

var _ oneOfValidator = tfsdk.AttributeValidator

type oneOfValidator struct {
  values []int64
}

func (v oneOfValidator) Description(ctx context.Context) string {/*...*/}
func (v oneOfValidator) MarkdownDescription(ctx context.Context) string {/*...*/}
func (v oneOfValidator) Validate(ctx context.Context, req tfsdk.ValidateAttributeRequest, resp *tfsdk.ValidateAttributeResponse) {/*...*/}

var _ noneOfValidator = tfsdk.AttributeValidator

type noneOfValidator struct {
  values []int64
}

func (v noneOfValidator) Description(ctx context.Context) string {/*...*/}
func (v noneOfValidator) MarkdownDescription(ctx context.Context) string {/*...*/}
func (v noneOfValidator) Validate(ctx context.Context, req tfsdk.ValidateAttributeRequest, resp *tfsdk.ValidateAttributeResponse) {/*...*/}

Then, create exported functions that return these:

func OneOf(values int64...) AttributeValidator {/*...*/}
func NoneOf(values int64...) AttributeValidator {/*...*/}

This would allow provider developers to declare attributes such as:

tfsdk.Attribute{
  // ... other fields ...
  Type: types.Int64,
  Validators: tfsdk.AttributeValidators{
    int64validator.OneOf(12, 24, 48), // or OneOf([]int64{12, 24, 48}...)
  },
},
