Returns ZX_ERR_NOT_FOUND if the server does not have metadata to provide. #### Request \ #### Response | Name | Type | |---|---| | `payload` | `https://fuchsia.dev/reference/fidl/fuchsia.driver.metadata#Metadata_GetPersistedMetadata_Result` | ## **STRUCTS** ### DictionaryEntry *Defined in [fuchsia.driver.metadata/dictionary.fidl](https://cs.opensource.google/fuchsia/fuchsia/+/main:sdk/fidl/fuchsia.driver.metadata/dictionary.fidl;l=18)* A key/value pair in a `Dictionary`.
| Field | Type | Description | Default | |---|---|---|---| | `key` | `string:1024` | The key for a dictionary entry. Nested dictionaries are represented by flattening the keys using '.' as a separator. For example, a key "a.b" with value 42 represents a dictionary "a" containing a key "b" with value 42. | No default | | `value` | `https://fuchsia.dev/reference/fidl/fuchsia.driver.metadata#DictionaryValue` | The value associated with the `key`. | No default | ### Metadata_GetPersistedMetadata_Response *Defined in [fuchsia.driver.metadata/fuchsia.driver.metadata.fidl](https://cs.opensource.google/fuchsia/fuchsia/+/main:sdk/fidl/fuchsia.driver.metadata/fuchsia.driver.metadata.fidl;l=12)* | Field | Type | Description | Default | |---|---|---|---| | `persisted_metadata` | `vector` | The persisted metadata. Assumed to be a persisted FIDL object. The actual type of the FIDL object is decided outside of this function. | No default | ## **TABLES** ### Dictionary *Defined in [fuchsia.driver.metadata/dictionary.fidl](https://cs.opensource.google/fuchsia/fuchsia/+/main:sdk/fidl/fuchsia.driver.metadata/dictionary.fidl;l=12)* A dictionary-like structure for generic metadata.
| Ordinal | Field | Type | Description | |---|---|---|---| | ### 1 | `entries` | `vector:1024` | A list of dictionary entries, where each entry is a (key, value) pair. | ## **UNIONS** ### DictionaryValue [flexible](https://fuchsia.dev/fuchsia-src/reference/fidl/language/language#strict-vs-flexible) *Defined in [fuchsia.driver.metadata/dictionary.fidl](https://cs.opensource.google/fuchsia/fuchsia/+/main:sdk/fidl/fuchsia.driver.metadata/dictionary.fidl;l=30)* A dictionary's value is an integer or a list of integers. | Ordinal | Variant | Type | Description | |---|---|---|---| | ### 1 | `int64` | `int64` | | | ### 2 | `int64_vec` | `vector:1024` | | | ### 3 | `str` | `string:32768` | | | ### 4 | `str_vec` | `vector:1024` | | | ### 5 | `boolean` | `bool` | |
