Module parser_database::ast

The AST data structure. It aims to faithfully represent the syntax of a Prisma Schema, with source span information.

Structs

• Argument
  An argument, either for attributes or for function call expressions.
• ArgumentsList
  A list of arguments inside parentheses.
• Attribute
  An attribute (following @ or `@@``) on a model, model field, enum, enum value or composite type field.
• AttributeId
  An attribute (@ or @@) node in the AST.
• CompositeType
  A type declaration in the data model. Defined by a type keyword and a block of fields that can be embedded in a model.
• CompositeTypeId
  An opaque identifier for a type definition in a schema AST. Use the schema[type_id] syntax to resolve the id to an ast::CompositeType.
• ConfigBlockProperty
  A named property in a config block.
• EmptyArgument
  An argument with a name but no value. Example:
• Enum
  An enum declaration. Enumeration can either be in the database schema, or completely a Prisma level concept.
• EnumId
  An opaque identifier for an enum in a schema AST.
• EnumValue
  An enum value definition.
• EnumValueId
  An opaque identifier for a value in an AST enum. Use the r#enum[enum_value_id] syntax to resolve the id to an ast::EnumValue.
• Field
  A field definition in a model or a composite type.
• FieldId
  An opaque identifier for a field in an AST model. Use the model[field_id] syntax to resolve the id to an ast::Field.
• GeneratorConfig
  A Generator block declaration.
• GeneratorId
  An opaque identifier for a generator block in a schema AST.
• Identifier
  An identifier.
• Model
  A model declaration.
• ModelId
  An opaque identifier for a model in a schema AST. Use the schema[model_id] syntax to resolve the id to an ast::Model.
• SchemaAst
  AST representation of a prisma schema.
• SourceConfig
  A source block declaration.
• SourceId
  An opaque identifier for a datasource block in a schema AST.
• Span
  Represents a location in a datamodel’s text representation.

Enums

• AttributeContainer
  A node containing attributes.
• AttributePosition
  In an model attribute definition
• EnumPosition
  A cursor position in a context.
• EnumValuePosition
  In an enum value.
• Expression
  Represents arbitrary, even nested, expressions.
• ExpressionPosition
• FieldArity
  An arity of a data model field.
• FieldPosition
  In a scalar field.
• FieldType
• IndentationType
  Defines the indentation of a PSL block.
• ModelPosition
  A cursor position in a context.
• NewlineType
  Defines the newline type of a PSL block.
• PropertyPosition
• SchemaPosition
  A cursor position in a schema.
• SourcePosition
• Top
  Enum for distinguishing between top-level entries
• TopId
  An identifier for a top-level item in a schema AST. Use the schema[top_id] syntax to resolve the id to an ast::Top.

Traits

• WithAttributes
  An AST node with attributes.
• WithDocumentation
  An AST node with documentation.
• WithIdentifier
  An AST node with an identifier.
• WithName
  An AST node with a name (from the identifier).
• WithSpan
  An AST node with a span.
