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 ⧉.

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

cargo install mini-functions

Divider

Usage

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

[dependencies]
mini-functions = "0.0.10"

Add the following to your main.rs file:

extern crate mini_functions;
use mini_functions::*;

then you can use the functions in your application code.

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:

cargo run --example <example-name>

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:

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:

cargo run --example example_claims

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:

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:

cargo run --example example_constants

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:

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:

cargo run --example example_date

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:

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:

cargo run --example example_errors

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:

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:

cargo run --example example_hash

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:

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:

cargo run --example example_logs

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:

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:

cargo run --example example_md5

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:

cargo run --example example_qr
