Pimalaya

Pimalaya is an ambitious project that aims to improve open-source tools related to Personal Information Management (as known as PIM) which includes emails, contacts, calendars, tasks and more.

Pimalaya has two objectives:

Provide I/O-free Rust libraries dedicated to the PIM domain. They serve as a basis for all sorts of top-level applications, which prevents developers to reinvent the wheel.
Provide quality house-made applications built on top of these libraries, gathered into projects.

Applications also share a small framework that is not shown above: pimalaya-cli, pimalaya-config and pimalaya-tui for argument parsing, configuration and terminal UI, plus pimconf for service discovery (autoconfig, DNS SRV, well-known URLs).
