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.
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.
