Version Diesel 2.2.0

This release wouldn’t be possible without the support of our contributors and sponsors. If you want to support diesels development, consider joining the reviewer team, submitting PR’s, help writing documentation or sponsor the maintainers.

Added

  • Support [print_schema] exclude_custom_type_definitions = ["Vector"]. If a custom type matches one element on the list it’s skipped.
  • Added automatic usage of all sqlite rowid aliases when no explicit primary key is defined for print-schema
  • Added a #[dsl::auto_type] attribute macro, allowing to infer type of query fragment functions
  • Added the same type inference on Selectable derives, which allows skipping specifying select_expression_type most of the time, in turn enabling most queries to be written using just a Selectable derive.
  • Added an optional #[diesel(skip_insertion)] field attribute to the Insertable derive macro, allowing fields which map to generated columns to be skipped during insertion.
  • Support for connection instrumentation. This allows to inspect any query run by your application
  • Logging in diesel-cli
  • Support for libsqlite3-sys 0.28
  • Add sqlite-integer-primary-key-is-bigint configuration option, usable with SQLite 3.37 or above, allowing to use BigInt for INTEGER PRIMARY KEY columns in SQLite for tables without the WITHOUT ROWID attribute (SQLite doc).
  • Support for multiple print_schema entry in diesel.toml (e.g. [print_schema.user1]), which allows generating multiple schema.rs files
  • Add support for COPY TO and COPY FROM statements
  • Add support for mapping chrono::Duration to postgresql’s INTERVAL sql type
  • Added serialize_database_to_buffer and deserialize_readonly_database_from_buffer methods in SqliteConnection to support serialization/deserialization of SQLite databases to and from byte buffers.
  • Added SerializedDatabase wrapper type for a serialized database that is dynamically allocated by calling serialize_database_to_buffer. This RAII wrapper deallocates the memory when it goes out of scope with sqlite3_free.

Changed

  • The minimal officially supported rustc version is now 1.78.0
  • Deprecated sql_function! in favour of define_sql_function! which provides compatibility with #[dsl::auto_type]
  • Deserialization error messages now contain information about the field that failed to deserialize
