Equation Solver

A equation solver as an API or usable as a cli application. Written in Rust.

Enter equation ← Output
-6 + 9/x = 3x ← Input

Output    Input
↓         ↓
Solve for x
x = {1, -3} ← Output

Installation

Clone the repository:

git clone https://github.com/AlphaCodingPilot/Equation-Solver.git

Usage (terminal)

1. Run the main.rs file in the src directory.
2. Enter an equation in the terminal.
3. Specify the variable you want to solve for after 'Solve for '

Usage (API)

1. Create an instance of equation_input::EquationInput using the equation_input::EquationInput::new(equation, variable_name) function, parsing the equation and the variable name you want to solve for as strings.
2. Use the solve_equation::solve_equation(input) function parsing the previously created equation-input. This returns a Result<equation_result::EquationResult, equation_error::EquationError> type.
3. Evaluate the result: the equation_result::EquationResult type has three variants: Solutions(Vec), Unsolvable, InfiniteSolutions { exceptions: Vec}. You can evaluate each of the equation_error::EquationError variants manually or get a log-message using the log_message() method.
