-/// Creates a `RuntimeGenesisConfig` JSON patch.
-///
-/// This macro creates a default `RuntimeGenesisConfig` initializing provided fields with given
-/// values, serialize it to JSON blob, and retain only the specified fields.
-///
-/// This macro helps to prevent errors that could occur from manually creating JSON objects, such
-/// as typos or discrepancies caused by future changes to the `RuntimeGenesisConfig` structure. By
-/// using the actual struct, it ensures that the JSON generated is valid and up-to-date.
-///
-/// This macro assumes that `serde(rename_all = "camelCase")` attribute is used for
-/// RuntimeGenesisConfig, what should be the case for frame-based runtimes.
-///
-/// # Example
-///
-/// ```rust
-/// use frame_support::runtime_genesis_config_json;
-/// #[derive(Default, serde::Serialize, serde::Deserialize)]
-/// #[serde(rename_all = "camelCase")]
-/// struct RuntimeGenesisConfig {
-///     a_field: u32,
-///     b_field: u32,
-///     c_field: u32,
-/// }
-/// assert_eq!(
-///     runtime_genesis_config_json! ({a_field:31, b_field:127}),
-///     serde_json::json!({"aField":31, "bField":127})
-/// );
-/// assert_eq!(
-///     runtime_genesis_config_json! ({a_field:31}),
-///     serde_json::json!({"aField":31})
-/// );
