Module sqlite 

Available on crate feature __sqlite-shared only.

Provides types and functions related to working with SQLite

Much of this module is re-exported from database agnostic locations. However, if you are writing code specifically to extend Diesel on SQLite, you may need to work with this module directly.

Re-exports

pub use self::query_builder::SqliteQueryBuilder;

Modules

authorizer

Types for the SQLite authorizer callback.

expression

Sqlite related query builder extensions.

query_builder

The SQLite query builder

sql_types

SQLite specific sql types

Structs

CollationNeededContext

Context passed to the collation-needed callback.

SerializedDatabase

SerializedDatabase is a wrapper for a serialized database that is dynamically allocated by calling sqlite3_serialize. This RAII wrapper is necessary to deallocate the memory when it goes out of scope with sqlite3_free.

Sqlite

The SQLite backend

SqliteBindCollectori-implement-a-third-party-backend-and-opt-into-breaking-changes

The BindCollector used by the SQLite backend.

SqliteBindCollectorDatai-implement-a-third-party-backend-and-opt-into-breaking-changes

SQLite bind collector data that is movable across threads.

SqliteBindValue

This type represents a value bound to a sqlite prepared statement

SqliteChangeEvent

Describes a single row change event from SQLite.

SqliteChangeOps

A bitmask of SQLite change operations used for filtering which events a hook should receive.

SqliteConnection

Connections for the SQLite backend. Unlike other backends, SQLite supported connection URLs are:

SqliteFunctionBehavior

Flags controlling SQLite custom function behavior.

SqliteReadOnlyBlob

A read only SQLite Blob

SqliteTraceFlags

Trace event mask selecting which events the callback receives.

SqliteUpdateRouter

Routes SQLite row-change events to per-table callbacks, selected by typed table! markers.

SqliteValue

Raw sqlite value as received from the database

WalCheckpointOutcome

The result of a wal_checkpoint run.

Enums

AuthorizerContext

Context information passed to the authorizer callback.

AuthorizerDecision

Authorizer callback decision.

AutoVacuumMode

The auto_vacuum mode of a database, controlling whether and when SQLite reclaims freed pages back to the file.

BusyDecision

The decision returned by an on_busy callback when the database is locked.

CommitDecision

The decision returned by an on_commit callback, controlling whether a pending commit completes.

JsonValidFlag

Flags for the json_valid function

OwnedSqliteBindValuei-implement-a-third-party-backend-and-opt-into-breaking-changes

An owned value bound to a SQLite prepared statement.

ProgressDecision

The decision returned by an on_progress callback, controlling whether a long-running query keeps executing.

SqliteBindValueRefi-implement-a-third-party-backend-and-opt-into-breaking-changes

The concrete bind value carried by a live SqliteBindCollector.

SqliteChangeOp

Identifies which kind of row change occurred.

SqliteLimit

SQLite resource limits that can be configured per-connection.

SqliteTextRep

Text encoding SQLite requested for a missing collation.

SqliteTraceEvent

Trace events delivered to the trace callback.

SqliteType

Determines how a bind parameter is given to SQLite

WalCheckpointMode

The mode of a wal_checkpoint run, matching the modes of sqlite3_wal_checkpoint_v2.

Traits

SqliteAggregateFunction

Trait for the implementation of a SQLite aggregate function

Functions

cancel_auto_extension

Removes a previously registered auto-extension, returning true if it was found (docs).

register_auto_extension

Registers an auto-extension that runs for every SQLite connection opened in this process, including non-Diesel ones.

reset_auto_extension

Clears all registered auto-extensions (docs).
