This crate implements the core of TaskChampion, the replica.

Users of this crate can manipulate a task database using this API, including synchronizing that task database with others via a synchronization server.

Example uses of this crate:

• user interfaces for task management, such as mobile apps, web apps, or command-line interfaces
• integrations for task management, such as synchronization with ticket-tracking systems or request forms.

Replica

A TaskChampion replica is a local copy of a user's task data. As the name suggests, several replicas of the same data can exist (such as on a user's laptop and on their phone) and can synchronize with one another.

Replicas are accessed using the Replica type.

Task Storage

Replicas access the task database via a storage object. Create a storage object with StorageConfig.

The storage module supports pluggable storage for a replica's data. An implementation is provided, but users of this crate can provide their own implementation as well.

Server

Replica synchronization takes place against a server. Create a server with ServerConfig.

The server module defines the interface a server must meet. Users can define their own server impelementations.

Feature Flags

Support for some optional functionality is controlled by feature flags.

• server-aws - sync to Amazon Web Services
• server-gcp - sync to Google Cloud Platform
• server-sync - sync to the taskchampion-sync-server
• sync - enables all of the sync features above
• bundled - activates bundling system libraries like sqlite
• tls-native-roots - use native (system) TLS roots, instead of those bundled with rustls, by (indirectly) enabling the rustls feature rustls-tls-native-roots.

By default, sync and bundled are enabled.
