## Overview

`Mini Functions` is a highly performant utility and wrapper functions library for Rust that has been carefully designed with optimization and efficiency in mind. By providing convenient wrapper functions, our library aims to provide a high-level interface for common tasks while still leveraging the performance benefits of Rust under the hood. These utility functions serve as an essential toolkit for any Rust developer, and the library's design abstractions allow for easy integration into a variety of projects and applications.

## Getting Started

It takes just a few minutes to get up and running with `mini-functions`.

### Requirements

The minimum supported Rust toolchain version is currently Rust **1.71.1** or later (stable).

### Installation

To install `mini-functions`, you need to have the Rust toolchain installed on your machine. You can install the Rust toolchain by following the instructions on the [Rust website ⧉][10].

Once you have the Rust toolchain installed, you can install `mini-functions` using the following command:

```shell

cargo install mini-functions

```

![Divider][divider]

## Usage

To use the `mini-functions` library in your project, add the following to your `Cargo.toml` file:

```toml

[dependencies]

mini-functions = "0.0.10"

```

Add the following to your `main.rs` file:

```rust

extern crate mini_functions;

use mini_functions::*;

```

then you can use the functions in your application code.

![divider][divider]

## Examples

The `mini-functions` library comes with a set of examples that demonstrate how to use the library. You can find the examples in the `examples` directory.

To run the examples, use the following command:

```shell

cargo run --example 

```

![divider][divider]

### Example 1: Working with JWT Claims

The `mini_functions` crate provides a Claims struct for working with JWT claims.

It contains the following functions:

- Setting Claims with `set_claim` to add claims.

- Getting Claims with `get_claim` to retrieve a claim value.

- Removing Claims with `remove_claim` to remove a claim.

Here is a full example:

```rust

let mut claims = Claims::new();

claims.set_claim("iss", "https://example.com");

claims.set_claim("admin", "true");

let admin = claims.get_claim("admin").unwrap();

claims.remove_claim("admin");

```

This allows setting, retrieving, and removing JWT claims conveniently.

To run the JWT Claims example, use the following command:

```shell

cargo run --example example_claims

```

![divider][divider]

### Example 2: Working with Mathematical Constants

The `mini_functions` crate provides access to common mathematical constants through the `Constants` struct and `cmn_constants` macro.

It contains the following functions:

- **Constants::new()** - Create a new Constants instance

- **constants()** - Get the full list of constants

- **constant(name)** - Lookup a constant by name

- **cmn_constants!** - Import constants into scope

Here is a full example:

```rust

use cmn::{constants::{Constant, ConstantValue}, cmn_constants};

let c = Constants::new();

let euler = c.constant("EULER").unwrap();

cmn_constants! {

    PI = cmn::constants::PI,

}

println!("Euler's constant: {euler}"); 

println!("Pi: {PI}");

```

This allows convenient access to mathematical constants.

To run the constants example:

```shell

cargo run --example example_constants

```

![divider][divider]

### Example 3: Working with Date and Time

The `mini_functions` crate provides a `DateTime` struct for working with dates and times.

It contains the following functions:

- `DateTime::now` - Get current date/time

- `DateTime::new` - Create a DateTime with default (UTC) timezone

- `DateTime::new_with_tz` - Create a DateTime with custom timezone

- `is_valid_day` - Check if a day value is valid

- `next_day`/`previous_day` - Get next/previous day

- `from_str` - Parse a date/time string

- `relative_delta` - Apply a delta to the DateTime

Here is an example:

```rust

let now = DateTime::now();

let tomorrow = now + chrono::Duration::days(1);

let yesterday = now - chrono::Duration::days(1);

println!("Today: {now}");

println!("Tomorrow: {tomorrow}"); 

println!("Yesterday: {yesterday}");

```

This allows convenient date/time handling.

To run the date/time example:

```shell

cargo run --example example_date

```

![divider][divider]

### Example 4: Error Handling

The `mini_functions` crate provides error handling functionality through the `ErrorType` enum.

It contains the following functions:

- `ErrorType::new` - Create new error type

- `new_subtype` - Create error subtype

Here is an example:

```rust

use mini_functions::errors::common::ErrorType;

let error = ErrorType::new("illegal_argument");

let sub_error = error.new_subtype("invalid_value");

println!("Main error: {error:?}");

println!("Sub-error: {sub_error:?}");

```

This allows simple error handling with custom types and subtypes.

To run the errors example:

```rust

cargo run --example example_errors

```

![divider][divider]

### Example 5: Password Hashing

The `mini_functions` crate provides password hashing and verification functions through the `Hash` struct.

It contains the following functions:

- `Hash::new_{algo}` - Generate a hash for a password

- `set_password` - Update password for a hash

- `verify` - Verify a password against a hash

- `to_string` - Convert hash to a string

Here is an example:

```rust

use mini_functions::hash::Hash;

let hash = Hash::new_argon2i("mypassword");

let is_valid = hash.verify("mypassword");

let updated_hash = hash.set_password("newpassword");

let new_is_valid = updated_hash.verify("newpassword");

```

This allows generating and verifying password hashes conveniently.

To run the password hashing example:

```rust

cargo run --example example_hash

```

![divider][divider]

### Example 7: Logging

The `mini_functions` crate provides application logging functionality through the `Log` struct.

It contains functions like:

- `Log::new` - Create a new log entry

- `LogFormat` - Supported log formats

Here is an example of logging events with different formats:

```rust

use mini_functions::logs::{Log, LogFormat, LogLevel};

let log_json = Log::new(

    "message-id", 

    "2023-01-01T12:00:00Z",

    LogLevel::Info,

    "AppEvent",

    "User logged in",

    LogFormat::JSON

);

let log_clf = Log::new(

    "message-id",

    "2023-01-01T12:00:00Z",

    LogLevel::Info,

    "AuthEvent",

    "User login successful",

    LogFormat::CLF

);

```

This allows flexible logging in various text and JSON formats.

To run the logging example:

```rust

cargo run --example example_logs

```

![divider][divider]

### Example 8: MD5 Hashing  

The `mini_functions` crate provides MD5 hash generation functionality through the `MD5` struct.

It contains functions like:  

- `MD5::hexdigest` - Generate MD5 hash for input

- `MD5::new` - Create MD5 hasher instance  

- `update` - Update hasher with new input

- `finalize` - Obtain final hash  

Here is an example of hashing different input sources:

```rust

use mini_functions::md5::MD5;

let digest = MD5::hexdigest("input string");

let mut hasher = MD5::new();

hasher.update(&[1, 2, 3]);

let hash = hasher.finalize();

```

This allows flexible hashing of strings, byte arrays, files.

To run the MD5 example:

```rust

cargo run --example example_md5

```

Here is an example:

```rust

use mini_functions::qr;

let qr_code = qr::QRCode::from_string("https://example.com");

let img = qr_code.to_png(512);

qr::save_png(&img, "qr.png");

```

This allows convenient QR code creation, manipulation and saving.

To run the QR code example:

```rust

cargo run --example example_qr

```

let mut rng = Random::new();

let rand_num = rand_int!(rng, 0, 10);

let rand_bool = rand_bool!(rng, 0.5);

```

This allows convenient random number generation.
