# kxio

`kxio` is a Rust library that provides injectable `FileSystem`, `Network` and
`Print` resources to enhance the testability of your code. By abstracting
system-level interactions, `kxio` enables easier mocking and testing of code
that relies on file system and network operations.

## Features

- **Filesystem Abstraction**
- **Network Abstraction**
- **Print Abstraction**
- **Enhanced Testability**

## Filesystem

The Filesystem module offers a clean abstraction over `std::fs`, the standard
file system operations. For comprehensive documentation and usage examples,
please refer to <https://docs.rs/kxio/latest/kxio/fs/>.

### Key Filesystem Features:

- File reading and writing
- Directory operations
- File metadata access
- Fluent API for operations like `.reader().bytes()`

## Network

The Network module offers a testable interface over the `reqwest` crate. For
comprehensive documentation and usage examples, please refer to
<https://docs.rs/kxio/latest/kxio/net/>

## Print

The Print module provides three implementations of the `Printer` trait:

- `StandardPrint` - behaves as normal, printing to `STDOUT` and `STDERR`
- `NullPrint` - swallows all prints, outputting nothing
- `TestPrint` - captures all print output and makes it available for assertions in tests

It also provides macros to use with each:

- `kxprintln`
- `kxprint`
- `kxeprintln`
- `kxeprint`

They are analogous to the `std` macros: `println`, `print`, `eprintln` and `eprint` respectively.

Each of the `kx{e}print{ln}` macros takes a reference to an instance of the `Printer` trait as the first parameter.

For comprehensive documentation and usage examples, please refer to <https://docs.rs/kxio/latest/kxio/print/>

## Getting Started

Add `kxio` to your `Cargo.toml`:

```toml
[dependencies]
kxio = "x.y.z"
```

## Usage

See the example [get.rs](./examples/get.rs) for an annotated example on how to use the `kxio` library.
It covers both the `net` and `fs` modules.

## Development

- The project uses [Cargo Mutants](https://crates.io/crates/cargo-mutants) for mutation testing.
- [ForgeJo Actions](https://forgejo.org/docs/next/user/actions/) are used for continuous testing and linting.
