Module butane_core::migrations::adb

source ·
Expand description

Abstract representation of a database schema. If using the butane CLI tool, there is no need to use this module. Even if applying migrations without this tool, you are unlikely to need this module.

Structs

  • AColumn
    Abstract representation of a database column schema.
  • ADB
    Abstract representation of a database schema.
  • ATable
    Abstract representation of a database table schema.

Enums

  • DeferredSqlType
    SqlType which may not yet be known.
  • Operation
    Individual operation use to apply a migration.
  • TypeIdentifier
    Identifier for a type as used in a database column. Supports both SqlType and identifiers known only by name. The latter is used for custom types. SqlType::Custom cannot easily be used directly at compile time when the proc macro serializing type information runs.
  • TypeKey
    Key used to help resolve DeferredSqlType

Functions

  • diff
    Determine the operations necessary to move the database schema from old to new.
