v1.0.0-alpha.3

Added

• #[schemars(transform = some::transform)] for applying arbitrary modifications to generated schemas. some::transform must be an expression of type schemars::transform::Transform - note that this can be a function with the signature fn(&mut Schema) -> ().
• SchemaSettings and SchemaGenerator are both now Send

Changed (⚠️ breaking changes ⚠️)

• visit module and Visitor trait have been replace with transform and Transform respectively. Accordingly, these items have been renamed:
  • SchemaSettings::visitors -> SchemaSettings::transforms
  • SchemaSettings::with_visitor -> SchemaSettings::with_transform
  • SchemaGenerator::visitors_mut -> SchemaGenerator::transforms_mut
  • GenVisitor -> GenTransform
  • Visitor::visit_schema -> Transform::transform
  • visit::visit_schema -> transform::transform_subschemas
• GenTransform must also impl Send, but no longer needs to impl Debug
• Doc comments no longer have newlines collapsed when generating the description property (#310)
