v0.7.0

Changed:

• BREAKING CHANGE - SchemaSettings can no longer be created using struct initialization syntax. Instead, if you need to use custom schema settings, you can use a constructor function and either:
  • assign it to a mut variable and modify its public fields
  • call the with(|s| ...) method on the settings and modify the settings inside the closure/function (as in the custom_settings.rs example)

Fixed:

• When deriving JsonSchema on structs, Option<T> struct fields are no longer included in the list of required properties in the schema (#11)
• Fix deriving JsonSchema when a non-std String type is in scope (#19)
• This will now compile: #[schemars(with="()")]

Added:

• Added allow_ref_siblings setting to SchemaSettings. When enabled, schemas with a $ref property may have other properties set.
• Can create JSON Schema 2019-09 schemas using SchemaSettings::draft2019_09() (which enables allow_ref_siblings)
