cargo-culture-kit

Overview

Core library for the cargo-culture project that provides the basic building blocks for running straightforward checks on a Rust project repo.

The primary intended application of these checks is within a command-line tool that contains and enforces best practices across repositories according to the needs of that organization.

The secondary envisioned application of these checks is integrated into Rust tests. This case may appeal to appeal to developers that want a rapid deep-integration path, don't mind writing a bit of code, and prefer to avoid the use of support programs.

Getting Started

Dependencies

cargo-culture-kit is a Rust project, and manages its dependencies with cargo, available as part of the standard Rust toolchain.

• rust

Building

For local program development, you can build cargo-culture-kit with:

• Download the project repository bash git clone https://github.com/PolySync/cargo-culture.git cd cargo-culture/cargo-culture-kit
• Execute a build bash cargo build

Installation

You can include cargo-culture-kit in your Rust project by adding to your Cargo.toml file.

• Added to the [dependencies] or `[dev-dependencies] section: toml cargo-culture-kit = "0.1"

Usage

check_culture_default is the easiest way to get started, as it provides a thin wrapper around the core check_culture function in combination with the Rules provided by the default_rules() function. Rule is the core trait of this crate. A Rule describes an idiom or best-practice for projects and provides a means of evaluating whether that rule of thumb is being upheld.

```rust use cargoculturekit::{checkculturedefault, IsSuccess, OutcomeStats}; use std::path::PathBuf;

let cargo_manifest = PathBuf::from("../cargo-culture/Cargo.toml"); let verbose = false;

let outcomes = checkculturedefault( cargo_manifest, verbose, &mut std::io::stdout() ) .expect("Unexpected trouble checking culture rules:");

let stats = OutcomeStats::from(outcomes); assert!(stats.issuccess()); asserteq!(stats.failcount, 0); asserteq!(stats.undetermined_count, 0); ```

Examples

• An example of implementing your own Rule: ```rust use cargoculturekit::{CargoMetadata, Rule, RuleContext, RuleOutcome}

  [derive(Clone, Debug, PartialEq)]

  struct IsProjectAtALuckyTime;

  impl Rule for IsProjectAtALuckyTime { fn description(&self) -> &str { "Should be lucky enough to only be tested at specific times." }

  fn evaluate(&self, context: RuleContext, ) -> RuleOutcome { use std::time::{SystemTime, UNIXEPOCH}; let sincetheepoch = match SystemTime::now().durationsince(UNIXEPOCH) { Ok(t) => t, Err() => return RuleOutcome::Undetermined, }; if sincetheepoch.assecs() % 2 == 0 { RuleOutcome::Success } else { RuleOutcome::Failure } } } ```

Tests

The cargo-culture-kit tests are managed through the standard cargo-integrated Rust test framework, with additional enhancement through the proptest property based testing library.

Building

To build but not run the tests:

bash cargo build --tests

Running

To both build and run the tests:

bash cargo test
