This crate contains the server/engine components of the Perspective data visualization suite. It is meant to be used in conjunction with the other crates of this project, e.g. perspective-client to create client connections to a server.

The [perspective] crate provides a convenient frontend for Rust developers, including both [perspective_client] and [perspective_server] as well as other convenient integration helpers.

Feature Flags

The following feature flags are available to enable in your Cargo.toml:

  • external-cpp Set this flag to configure this crate's compile process to look for Perspective C++ source code in the environment rather than locally, e.g. for when you build this crate in-place in the Perspective repo source tree.
