Remove initialize_crypto. We use rustls as is. You can configure a non-default behavior of
rustls with
install_default (1).
Merge HdbError variants Usage and UsageDetailed, as well as Impl and ImplDetailed,
new variants Usage and Impl are based on Cow.
Increase MSRV to 1.80, due to update of bb8 (2).
Version bump due to (1) and (2).
Add method ConnectParamsBuilder::to_url_with_password().
Improve handling of ExecutionResults.
Fix wrong sequence of entries in HdbResponse.
Remove ConnectParamsBuilder::to_url() (use ConnectParamsBuilder::to_url_without_password()
instead).
Add ConnectParamsBuilder::to_url_without_password().
Deprecate ConnectParamsBuilder::to_url().
Add hdbconnect(_async)::initialize_crypto() to allow reliable rustls initialization without
direct dependency to rustls.
Switch to serde_db 0.12 and adopt its improved naming (-> version bump).
Remove Tls from public API, as it is not needed there.
Fix implementation of url-option "insecure_omit_server_certificate_check".

Add some Clone implementations.
Allow configuring the cursor holdability.
Further minor improvements.
Add bb8 pool for hdbconnect_async.

Code maintenance
Fix issue in CLob.
Revise lob reading and buffering.
Add two HdbError variants to better handle connection failures.
Improve code examples.
Re-introduce some getter methods on ConnectParamsBuilder.
ConnectionConfiguration can be used to finetune hdbconnect.
ConnectionStatistics provides some statistics about the use of a concrete connection.
The async variant uses tokio's mutex, which has no issue with poisoning. Many methods of the async variant thus do not need to wrap their return value into a Result. Those wrappings are now removed.
hdbconnect and hdbconnect_async now support and use by default the compression capability of
the HANA SQL protocol for large requests and responses.
Various API methods in hdbconnect_async now return T rather than Result<T>.
Most Connection methods don't require mutability.
Introduce variants HdbValue::DBSTRING and HdbError::Cesu8AsBytes
for late handling of cesu8 errors. Late handling is important to ensure that reply-parsing
is always completed so that no data remain on the wire.
Re-export serde_db's (de)serialization errors.
Fix READMEs.
Reorganize the project using three workspaces.
Add a sibling crate hdbconnect_async!!

Add redirect support: target database can be specified by name.
Some minor API smoothing (-> version bump):
- Connection::
get_database_name(),get_system_id(), andget_full_version_string(), returnHdbResult<String>, rather thanHdbResult<Option<String>> - ConnectParamsBuilder
get_passwordreturns aSecUtf8instead of aSecStrget_optionsis removed
Add support for array-type.
Minor improvements, code maintenance.
Revise handling of ResultSetMetadata to make it much more ergonomic (and idiomatic).
- ResulSset now provides direct access to a
Vec<FieldMetadata>, andFieldMetadataexposes the metadata of each field. - The type
ResultSetMetadatawith its awkward API is gone (-> version bump).
Update dependencies.
Fix issue with empty LOBs being read from the database (introduced with 0.21.3).
Update dependencies.
Implement automatic reconnect (only works within the server's reconnect-wait-timeout).
Make HdbError thread-safe (again) - Kudos to Mark Obad!
Minor performance improvement in LOB implementation.

Add support for CONNECT (switch user).
Simplify API of OutputParameters.

Improve ease-of-use for lob objects by letting lob objects keep their result set core object and their prepared statement core object alive until they are completely loaded.
Add Connection::client_info.
Add value conversions from Strings to number types (using std::fmt::Display)
and from number types to Strings (using parse()).
Change serialization format of ConnectParamsBuilder to URL; the serialization to url includes all information except password.
Some code maintenance.
Add variant ServerCerts::None to use TLS without server validation.
Replace &String with &str in return value types.
Make ResultsSet thread-safe.
Add IntoConnectParamsBuilder and implementations for &str and String and Url.
Make Connection::new() and ConnectionManager::new() more flexible by
taking a P: IntoConnectParams rather than a ConnectParams.
Improve ConnectParamsBuilder:
- move root-certificates option as an additional variant into ServerCerts enum
- don't erase any information from the
ConnectParamsBuilderduring build()
Make feature "tls" permanent - so it disappears from the list of cargo features!
Remove redundant ConnectParams in Connection (it is in AmConnCore anyway).
Remove wrong debug asserts from lob_writer (adding to the fix for issue 23).
Implement Display, and derive Debug, for ConnectParams.
Fix pedantic clippies, and some docu.
Revise HdbResponse:
- remove public visibility to its elements (-> version bump)
- remove parameter descriptors
Simplify handling of ParameterDescriptors in PreparedStatement.
Make ParameterDescriptors public.
Support database procedures with LOB input parameters (fix issue 23).
Bugfix: Let ResultSets that were produced from a PreparedStatement keep
the PreparedStatement's Core alive.
Add option to use Mozillas root certificates.
Version bump due to incompatible API changes caused by
- Avoid cloning of metadata
- Use inner mutability to avoid mut for ResultSet iterations
- Revise handling of server usage information
Stick to older version of rustls (0.15.1) and webpki (0.19.1) to stay compatible with actix.
Add convenience method Connection::prepare_and_execute().
Incompatible: revise API of OutputParameters:
allow iterating and using deserialization with serde_db, revise method names.

Add possibility to set the lob-write-length.
Increase default values for fetch-size and lob-read-length.
Fix broken TLS feature.
Change HdbValue::LOBSTREAM to LOBSTREAM(Option<Arc<Mutex<Read + Send>>>).

Add HdbValue::STR(&str), and allow LOB streaming to the database with HdbValue::LOBSTREAM.
Add support for database columns of types ALPHANUM and BINTEXT.
Improve HdbValue, TypedId, and handling of parameters in PreparedStatement. Add method PreparedStatement.execute_row().

- Reduce complexity of HdbValue: use a single explicit NULL variant
- Also simplify type id handling
- Implement geo-types
- Migrate to serde_db 0.7
- Apply changes to ResultSet
- remove methods pop_row(), reverse_rows(),
- add method next_row()
- make ResultSet an Iterator for item type HdbResult<Row>
