JSON Parser

This is a small, educational JSON parser written in Rust.

• Purpose: my very first JSON parser implementation and my first finished Rust program, built as a study project to learn parsing and Rust.
• Status: proof-of-concept / learning project.

Features

• Supports parsing JSON objects and arrays.
• Recognizes strings, numbers (decimal and negative), booleans (true / false) and null.
• Returns a simple AST (Abstract Syntax Tree) represented by the JsonType enum.

Limitations

• No support for escaped characters inside strings (e.g. \", \\, \n).
• Scientific notation for numbers (exponents e, E) is not implemented and will panic if encountered.
• Not meant for production use, it is a learning exercise and intentionally minimal.
