Abscissa is a microframework for building Rust applications (either CLI tools or network/web services), aiming to provide a large number of features with a minimal number of dependencies, and with a strong focus on security.

Documentation

Features

• command-line option parsing: simple declarative option parser based on (i.e. forked from) [gumdrop]. The option parser in Abcissa contains numerous improvements which provide better UX and tighter integration with the other parts of the framework (e.g. overriding configuration settings using command-line options).
• configuration: declarative global configuration support using an RwLock on a lazy_static. Simple parsing of TOML configurations to serde-parsed global structures which can be dynamically updated at runtime.
• error handling: generic Error type based on the failure crate, and a unified error-handling subsystem.
• logging: uses the log and simplelog crates to automatically configure application-level logging, presently to standard output or files.
• secrets management: the (optional) secrets module includes a Secret type which derives serde's Deserialize and can be used to represent secret values parsed from configuration files or elsewhere (e.g. credentials loaded from the environment or network requests)
• shell interactions: support for colored terminal output (with color support autodetection). Useful for Cargo-like status messages with easy-to-use macros.

Frequently Asked Questions (FAQ)

Q1: Why is it called "abscissa"?

A1: An abscissa represents the elevation of a point above the y-axis. In that regard, "Abscissa" can be thought of as a pun about getting off the ground, or elevating your project.

The word "abscissa" is also the key to the Kryptos K2 panel.
