PoE Gem Parser in Rust

A parser for normal gems from game "Path of Exile" written in Rust. Parser is written using pest library and can extract various fields(name, tags, level, requirements, etc.) of the selected gem. That project can be further extended for parsing not only gems, but also transfigured/vaal gems, items, fragments, etc. (Gem text for testing can be taken from Path of Exile's trade site)

Description

Parser reads input string from arguments or file and splits it into components using predifined pest grammar rule, that components are later combined in a ParsedGem structure.

Developed grammar rules

WHITESPACE - any whitespace characters
separator - separator between blocks
gem - complete gem grammar rule
item_class - class of item with "Item class:" string
class - class of item
rarity - rarity type of item with "Rarity:" string
rarity_type - rarity type
name - name of item
tags - tags of item
level - level of gem with "Level:" and "(Max)" strings
gem_level - level of gem
gem_changes - stats that are changed using this gem
quality - quality of gem with "Quality:" and "(augmented)" strings
gem_quality - quality of gem
requirements - requirements this gem with "Requirements:" string
requirement - one of requirements
description - description of the gem
modifiers - modifiers of gem
usage - how that gem should be used in a game
corrupted - is item corrupted or not
note - note

Exceptional, Support         --------- tags = ["Exceptional", "Support"]
Level: 2                     --------- level = 2
Reservation Multiplier: 96%  --------- gem_changes = ["Reservation Multiplier: 96%"]
Quality: +9% (augmented)     --------- quality = 9
--------
Requirements:                --------- requirements = ["Level: 1"]
Level: 1                 
--------
Supports any skill gem       --------- description = "Supports any skill gem"
