1/// Generates a [`RootSchema`](crate::schemars::schema::RootSchema) for the given type using default settings.
2///
3/// The type must implement [`JsonSchema`](crate::schemars::JsonSchema).
4///
5/// The schema version is strictly `draft-07`.
6///
7/// # Example
8/// ```
9/// use cosmwasm_schema::schema_for;
10/// use schemars::JsonSchema;
11///
12/// #[derive(JsonSchema)]
13/// struct MyStruct {
14///     foo: i32,
15/// }
16///
17/// let my_schema = schema_for!(MyStruct);
18/// ```
