Crate bonsaidb_server

BonsaiDb’s networked database implementation.

This crate implements BonsaiDb’s networked database implementation. The Server and CustomServer<Backend> types provide their most common functionality by implementing the StorageConnection.

This crate supports two methods for exposing a BonsaiDb server: QUIC and WebSockets.

QUIC is a new protocol built atop UDP. It is designed to operate more reliably than TCP, and features TLS built-in at the protocol level. WebSockets are an established protocol built atop TCP and HTTP.

Our user’s guide has a section covering setting up and accessing a BonsaiDb server.

Minimum Supported Rust Version (MSRV)

While this project is alpha, we are actively adopting the current version of Rust. The current minimum version is 1.58, and we plan on updating the MSRV to implement namespaced Features as soon as the feature is released.

Feature Flags

By default, the full feature is enabled. These features are prefixed by server- when being enabled from the omnibus bonsaidb crate.

• full: Enables all the flags below,
• acme: Enables automtic certificate acquisition through ACME/LetsEncrypt.
• cli: Enables the cli module.
• encryption: Enables at-rest encryption.
• hyper: Enables convenience functions for upgrading websockets using hyper.
• instrument: Enables instrumenting with tracing.
• pem: Enables the ability to install a certificate using the PEM format.
• websockets: Enables WebSocket support.
• password-hashing: Enables the ability to use password authentication using Argon2.

Traits

ApplicationProtocols

A collection of supported protocols for a network service.

Backend

Tailors the behavior of a server to your needs.

CustomApiDispatcher

A trait that can dispatch requests for a CustomApi.

HttpService
