Use Cases or Problem Statement
Provider developers should be able to generically validate that every types.Map element key or value can be generically validated.
Proposal
Inside a mapvalidator package, create new unexported types that satisfies the tfsdk.AttributeValidator interface:
var _ keysAreValidator = tfsdk.AttributeValidator
type keysAreValidator struct {
keyValidators []AttributeValidators
}
func (v keysAreValidator) Description(ctx context.Context) string {/*...*/}
func (v keysAreValidator) MarkdownDescription(ctx context.Context) string {/*...*/}
func (v keysAreValidator) Validate(ctx context.Context, req tfsdk.ValidateAttributeRequest, resp *tfsdk.ValidateAttributeResponse) {/*...*/}
var _ valuesAreValidator = tfsdk.AttributeValidator
type valuesAreValidator struct {
valueValidators []AttributeValidators
}
func (v valuesAreValidator) Description(ctx context.Context) string {/*...*/}
func (v valuesAreValidator) MarkdownDescription(ctx context.Context) string {/*...*/}
func (v valuesAreValidator) Validate(ctx context.Context, req tfsdk.ValidateAttributeRequest, resp *tfsdk.ValidateAttributeResponse) {/*...*/}Then, create an exported function that returns it:
func KeysAre(keyValidators AttributeValidator...) AttributeValidator {/*...*/}
func ValuesAre(valueValidators AttributeValidator...) AttributeValidator {/*...*/}This would allow provider developers to declare attributes such as:
tfsdk.Attribute{
// ... other fields ...
Type: types.Map{
ElemType: types.String,
},
Validators: tfsdk.AttributeValidators{
mapvalidator.KeysAre(
stringvalidator.LengthBetween(1, 255),
stringvalidator.RegexMatches(regexp.MustCompile(`^[a-z]+$`), "must contain only lowercase alphabetical characters")
),
},
