# FeatureFlagInfo

A provider used to access information about config\_feature\_flag rules.

## Members

* [error](#error)
* [is\_valid\_value](#is_valid_value)
* [to\_json](#to_json)
* [to\_proto](#to_proto)
* [value](#value)

## error

```
string FeatureFlagInfo.error
```

If non-None, this error was generated when trying to compute current value of flag.
May return `None`.

## is\_valid\_value

```
bool FeatureFlagInfo.is_valid_value(value)
```

The value of the flag in the configuration used by the flag rule.

### Parameters

| Parameter | Description                                                      |
| --------- | ---------------------------------------------------------------- |
| `value`   | required  String, the value to check for validity for this flag. |

## to\_json

```
string FeatureFlagInfo.to_json()
```

**Deprecated**. This API is deprecated and will be removed soon. Please do not depend on it. It is *disabled* with `---incompatible_struct_has_no_methods`. Use this flag to verify your code is compatible with its imminent removal.
Creates a JSON string from the struct parameter. This method only works if all struct elements (recursively) are strings, ints, booleans, other structs, a list of these types or a dictionary with string keys and values of these types. Quotes and new lines in strings are escaped. Examples:

```
struct(key=123).to_json()
# {"key":123}

struct(key=True).to_json()
# {"key":true}

struct(key=[1, 2, 3]).to_json()
# {"key":[1,2,3]}

struct(key='text').to_json()
# {"key":"text"}

struct(key=struct(inner_key='text')).to_json()
# {"key":{"inner_key":"text"}}

struct(key=[struct(inner_key=1), struct(inner_key=2)]).to_json()
# {"key":[{"inner_key":1},{"inner_key":2}]}

struct(key=struct(inner_key=struct(inner_inner_key='text'))).to_json()
# {"key":{"inner_key":{"inner_inner_key":"text"}}}
```

.

Deprecated: instead, use json.encode(x) or json.encode\_indent(x), which work for values other than structs and do not pollute the struct field namespace.

## to\_proto

```
string FeatureFlagInfo.to_proto()
```

**Deprecated**. This API is deprecated and will be removed soon. Please do not depend on it. It is *disabled* with `---incompatible_struct_has_no_methods`. Use this flag to verify your code is compatible with its imminent removal.
Creates a text message from the struct parameter. This method only works if all struct elements (recursively) are strings, ints, booleans, other structs or dicts or lists of these types. Quotes and new lines in strings are escaped. Struct keys are iterated in the sorted order. Examples:

```
struct(key=123).to_proto()
# key: 123

struct(key=True).to_proto()
# key: true

struct(key=[1, 2, 3]).to_proto()
# key: 1
# key: 2
# key: 3

struct(key='text').to_proto()
# key: "text"

struct(key=struct(inner_key='text')).to_proto()
# key {
#   inner_key: "text"
# }

struct(key=[struct(inner_key=1), struct(inner_key=2)]).to_proto()
# key {
#   inner_key: 1
# }
# key {
#   inner_key: 2
# }

struct(key=struct(inner_key=struct(inner_inner_key='text'))).to_proto()
# key {
#    inner_key {
#     inner_inner_key: "text"
#   }
# }

struct(foo={4: 3, 2: 1}).to_proto()
# foo: {
#   key: 4
#   value: 3
# }
# foo: {
#   key: 2
#   value: 1
# }
```

Deprecated: use proto.encode\_text(x) instead.

## value

```
string FeatureFlagInfo.value
```

The current value of the flag in the flag's current configuration. None if there is an error.
May return `None`.
