Structs

• Migrator

• SqlxDatabase
  The SqlxDatabase struct is used to create a database:

Enums

• SqlxType
  This enum represents the set of types that we currently support in our database Since we support only Sqlite at the moment, those types are close to what is supported by Sqlite: https://www.sqlite.org/datatype3.html

Traits

• FromSqlxError
  This trait provides some syntax for transforming sqlx errors into ockam errors
• MigrationSet
  This trait runs migrations on a given database
• RustMigration
  Individual rust migration
• ToSqlxType
  This trait can be implemented by any type that can be converted to a database type Typically an Identifier (to a Text), a TimestampInSeconds (to an Integer) etc…
• ToVoid
  This trait provides some syntax to shorten queries execution returning ()
