Types related to database connections
Modules§
- Helper types for prepared statement caching
Structs§
- An implementation of
TransactionManagerwhich can be used for backends which use ANSI standard syntax for savepoints such as SQLite and PostgreSQL. - The default loading mode provided by a
Connection. - Various status fields to track the status of a transaction manager with a started transaction
- A helper type that allows printing out str slices
- Valid transaction status for the manager. Can return the current transaction depth
Enums§
- This enum describes possible connection events that can be handled by an
Instrumentationimplementation - Represents a change to apply to the depth of a transaction
- Status of the transaction manager
Traits§
- A variant of the
Connectiontrait that is usable with dynamic dispatch - A connection to a database
- This trait restricts who can implement
Connection - A helper trait for opaque query representations which allows to get a
DisplayandDebugrepresentation of the underlying type without exposing type specific details - A type that provides an connection
Instrumentation - The specific part of a
Connectionwhich actually loads data from the database - This trait provides helper methods to convert a database lookup type to/from an
std::any::Anyreference. This is used internally by the#[derive(MultiConnection)]implementation - Perform simple operations on a backend.
- Manages the internal transaction state for a connection.
- Describes a connection with an underlying
crate::sql_types::TypeMetadata::MetadataLookup
Functions§
- Get an instance of the default
Instrumentation - Set a custom constructor for the default
Instrumentationused by new connections
