Instead, use last_insert_rowid() function to find the row.
There is no race condition in using last_insert_rowid(), because
last_insert_rowid() returns row id last inserted in this connection. As
we hold the connection during the whole transaction, it is impossible
that some other thread will execute INSERT statement in parallel.
This commit is part of the effort to get rid of sql::get_rowid hack and
use transactions more for related SQL statements.
Existing public methods that use these functions, like sql::execute, are
only suitable for executing a single statement.
Sometimes it is useful to execute multiple statements within one
connection, for example to begin a transaction, execute mutliple SELECT
and INSERT queries and commit or rollback the whole transaction.
We already have a .strdup() method on AsRef<str>, this adds this
method also to an option of this. In case the option is None a NULL
pointer is returned.
This is done by using a new trait, as the type system otherwise
considers such an implementation conflicting with the existing one.
Now configure module is no longer public. Users should call
Context.configure() and Context.is_configured() methods.
Configure module is completely hidden from documentation unless
--document-private-items option is specified.
RFC 2183 specifically allows filenames to be specified for MIME parts
with "inline" Content-Disposition.
Previously we treated such attachments as an error, causing the whole
message parsing to fail. Now it is only an error if Content-Disposition
cannot be parsed.
MIME parts with filename are now considered to be attachments
regardless of their Content-Disposition type. However, "attachment"
Content-Disposition is still processed differently: we generate a
filename for it even if it is not specified.
I had a look for two mintues at converting things to .try_inner() and
I don't think this is currently worth the effort or would increase
readability a lot. So let's leave this for now.
There is no need to have both a .log_warn() and .log_err(), even their
names are confusing by now. Let's just have the most liberal one and
reduce one more thing we need to know about.
Also, these traits don't need to be pub.
