SubModel

The project is not completed

progress

• load necessary SubModel information from marco input
• generate codes
• field type mapping
• extra sub model field
• support Generic
• condition field type mapping
• a better way to add extra proc_marco onto field on SubModels

usage

using all or none define sub model type

• all default all of the field is a part of the sub model
• none default is an empty struct

in the all or none

• if only need define the name of sub model, can use like that

#[sub_model(all("foo"),none("foo2"))]

• or else using full pattern name = "foo"

there a a set of information can be define

• vis the visibility of the sub model, default pub
• name the name of the sub model
• extra_field the extra field of the sub model, can use like that
  • the ty define the type of extra field
  • the from define how to create the value in this field, it accept a path to a function without any params

#[all(
    name = "foo",
    extra_field(
        foo(ty = "bool", from = "Default::default")
))]

the example add a new field named foo with type bool,create by Default::default to sub model foo

• extra other marco that add to this new sub model, for example

#[all(
    name = "foo",
    extra(
        derive(Debug, Serialize, Deserialize)
))]

the example make the sub model foo can serialize and deserialize
