Module quaint::connector

A set of abstractions for database connections.

Provides traits for database querying and executing, and for spawning transactions.

Connectors for MySQL, PostgreSQL, SQLite and SQL Server connect to the corresponding databases and implement the Queryable trait for generalized querying interface.

Structs

• DefaultTransaction
  A default representation of an SQL database transaction. If not commited, a transaction will be rolled back by default when dropped.
• Mssql
  A connector interface for the SQL Server database.
• MssqlUrl
  Wraps a connection url and exposes the parsing logic used by Quaint, including default values.
• Mysql
  A connector interface for the MySQL database.
• MysqlError
  This type represents MySql server error.
• MysqlUrl
  Wraps a connection url and exposes the parsing logic used by quaint, including default values.
• PostgreSql
  A connector interface for the PostgreSQL database.
• PostgresError
• PostgresUrl
  Wraps a connection url and exposes the parsing logic used by Quaint, including default values.
• ResultRow
  An owned version of a Row in a ResultSet. See ResultRowRef for documentation on data access.
• ResultRowRef
  A reference to a Row in a ResultSet. The columns can be accessed either through their position or using the column name.
• ResultSet
  Encapsulates a set of results and their respective column names.
• ResultSetIterator
  Thin iterator for ResultSet rows. Might become lazy one day.
• Sqlite
  A connector interface for the SQLite database
• SqliteError
• SqliteParams
  Wraps a connection url and exposes the parsing logic used by Quaint, including default values.
• SslParams

Enums

• ConnectionInfo
  General information about a SQL connection.
• EncryptMode
  TLS mode when connecting to SQL Server.
• IsolationLevel
  Controls the locking and row versioning behavior of connections or transactions. The levels correspond to the ANSI standard isolation levels, plus Snapshot for SQL Server.
• PostgresFlavour
• SqlFamily
  One of the supported SQL variants.
• SslAcceptMode

Constants

• DEFAULT_MYSQL_DB

Traits

• GetRow
• Queryable
  Represents a connection or a transaction that can be queried.
• TakeRow
• ToColumnNames
• Transaction
• TransactionCapable
  A thing that can start a new transaction.
• ValueIndex

Functions

• params_from_iter
  Constructor function for a ParamsFromIter. See its documentation for more.
• sqlite_version
