Derive Macros

EntityModel

The EntityModel derive macro is the 'almighty' macro which automatically generates Entity, Column, and PrimaryKey from a given Model.

Entity

The DeriveEntity derive macro will implement EntityTrait for Entity and it assumes Model, Column, PrimaryKey and Relation exist in the current scope. It also provides implementation of Iden and IdenStatic for Entity.

Column

The DeriveColumn derive macro will implement ColumnTrait for Columns. It defines the identifier of each column by implementing Iden and IdenStatic. The EnumIter is also derived, allowing iteration over all enum variants.

Primary Key

The DerivePrimaryKey derive macro will implement PrimaryKeyToColumn for PrimaryKey which defines tedious mappings between primary keys and columns. The EnumIter is also derived, allowing iteration over all enum variants.

Model

The DeriveModel derive macro will implement ModelTrait for Model, which provides setters and getters for all attributes in the model. It also implements FromQueryResult to convert a query result into the corresponding Model.

Active Model

The DeriveActiveModel derive macro will implement ActiveModelTrait for ActiveModel which provides setters and getters for all active values in the active model.

Active Enum

The DeriveActiveEnum derive macro will implement ActiveEnum for any enums.

Relation

The DeriveRelation derive macro will implement RelationTrait for Relation.

Iterable

The EnumIter derived macro will implement Iterable to allow iteration over all enum variants.
