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.
Since stock string callback has been deprecated, all event callbacks
return 0.
For compatibility, C declarations are not changed and FFI users are
expected to return 0 from their callbacks.
A new context is now created by calling Context::new and therefore you
always have a valid context. This is much more in Rust style and will
allow a lot of furture simplifications on the context itself.
The FFI layer has not yet been adjusted in this commit and thus will
fail.
This removes the dc_context_unref function from the Rust API which was
just an alias for dc_close. It still exists on the C API where it
makes sure to free the memory.
It also implements Drop for the context which just calls dc_close to
make sure all the memory is freed. Since you can call dc_close as
many times as you like this ensures that at the Rust level you can't
Drop the struct without releasing the memory.
Finally since memory is now freed by dropping the struct this removes
the #[repr(C)] for the struct. This struct is fully opaque to the C
API.
Add a trait for str.strdup() to replace to_cstring() which avoid the
signature ambiguity with .to_string().
Also instruduce CString::yolo() as a shortcut to
CString::new().unwrap() and use it whenever the variable does can be
deallocated by going out of scope. This is less error prone.
Use some Path.to_c_string() functions where possible.
This new command attempts to send malformed utf8 string to current chat with
dc_send_text_msg() function. Currently, instead of error code it causes
application crash with following backtrace:
thread 'main' panicked at 'Non utf8 string: '[255]' (Utf8Error { valid_up_to: 0, error_len: Some(1) })', src/dc_t
