Database.HsSqlPpp.Annotation

Contains the annotation data types and a few auxiliary functions.

Annotation data types

data Annotation

Annotation type - one of these is attached to most of the data types used in the ast. the fields in order are:

Constructors

Annotation

Fields

• anSrc :: Maybe SourcePosition

  source position for this node

• anType :: Maybe TypeExtra

  type of the node, Nothing if the tree hasn't been typechecked or if a type error elsewhere prevents determining this node's type

• anErrs :: [TypeError]

  any type errors

• anImplicitCast :: Maybe TypeExtra

  if an implicit cast is needed between this node an its parent, this the target type of cast. If no implicit cast is needed, this is Nothing

• anCatUpd :: [CatalogUpdate]

  any catalog updates that a statement produces, used only for ddl Statements
