mimeparser now handles try_decrypt() errors instead of simply logging them. If try_decrypt() returns an error, a single message bubble with an error is added to the chat. The case when encrypted part is found in a non-standard MIME structure is not treated as an encryption failure anymore. Instead, encrypted MIME part is presented as a file to the user, so they can download the part and decrypt it manually. Because try_decrypt() errors are handled by mimeparser now, try_decrypt() was fixed to avoid trying to load private_keyring if the message is not encrypted. In tests the context receiving message usually does not have self address configured, so loading private keyring via Keyring::new_self() fails together with the try_decrypt().

Deltachat-core written in Rust
Installing Rust and Cargo
To download and install the official compiler for the Rust programming language, and the Cargo package manager, run the command in your user environment:
$ curl https://sh.rustup.rs -sSf | sh
On Windows, you may need to also install Perl to be able to compile deltachat-core.
Using the CLI client
Compile and run Delta Chat Core command line utility, using cargo:
$ RUST_LOG=repl=info cargo run --example repl --features repl -- ~/deltachat-db
where ~/deltachat-db is the database file. Delta Chat will create it if it does not exist.

If yourfriend@email.org uses DeltaChat, but does not receive message just
sent, it is advisable to check Spam folder. It is known that at least
gmx.com treat such test messages as spam, unless told otherwise with web
interface.

Installing libdeltachat system wide
$ git clone https://github.com/deltachat/deltachat-core-rust.git
$ cd deltachat-core-rust
$ cmake -B build . -DCMAKE_INSTALL_PREFIX=/usr
$ cmake --build build
$ sudo cmake --install build
Development
# run tests
$ cargo test --all
# build c-ffi
$ cargo build -p deltachat_ffi --release
Debugging environment variables
-
DCC_IMAP_DEBUG: if set IMAP protocol commands and responses will be printed -
DCC_MIME_DEBUG: if set outgoing and incoming message will be printed -
RUST_LOG=repl=info,async_imap=trace,async_smtp=trace: enable IMAP and SMTP tracing in addition to info messages.
Expensive tests
Some tests are expensive and marked with #[ignore], to run these
use the --ignored argument to the test binary (not to cargo itself):
$ cargo test -- --ignored
