ion: Advanced Ion File Parser

Overview

ion is a sophisticated parser for *.ion files, crafted in Rust to handle a versatile data format. This format is ideal for configurations and structured data, supporting a diverse range of types like String, Integer (i64), Float (f64), Boolean, Arrays, and Dictionary.

Features

• Diverse Data Type Support: Capable of parsing Strings, Integers, Floats, Booleans, Arrays, and Dictionaries.
• Section-based Organization: Facilitates data organization in distinct sections with varied structures.
• Efficient Parsing: Optimized for performance and reliability in parsing complex Ion documents.

Example Usage

The following examples demonstrate the flexibility and structure of *.ion files:

Basic Section

[CONTRACT]
id = "HOTEL001"
name = "Hotel001"
currency = "EUR"
active = true
markets = ["DE", "PL"]

Table Format

[DEF.MEAL]
| code | description |
|------|-------------|
| RO   | Room Only   |

[DEF.ROOM]
| code | description |      occ       |
|------|-------------|----------------|
| SGL  | Single      | P1:2 A1:1 C0:1 |
| DBL  | Double      | P2:3 A2:2 C0:1 |

Basic section with possible field types

[CONTRACT]
country = "Poland"                  // String
markets = ["PL", "DE", "UK"]        // Array
75042 = {                           // Dictionary
    view = "SV"                     // String
    loc  = ["M", "B"]               // Array
    dist = { beach_km = 4.1 }       // Dictionary
}

Complex document built from few sections

[CONTRACT]
country = "Poland"
markets = ["PL", "DE", "UK"]
75042 = {
    view = "SV"
    loc  = ["M", "B"]
    dist = { beach_km = 4.1 }
}

[RATE.PLAN]
|       dates       | code |  description   |    rooms    | rules |
|-------------------|------|----------------|-------------|-------|
| 20200512:20200514 | BAR  | Best available | SGL,DBL,APP |       |
| 20200601:20200614 | BBV  | Best Bar View  | DBL,APP     |       |

# A `key-value` and `table` section
[RATE.BASE]
enable = true
legend = {
    UN = "unit night"
    RO = "room only"
}
|       dates       | charge | room | occ | meal |  amt   |
|-------------------|--------|------|-----|------|--------|
| 20161122:20170131 | UN     | APP  | A2  | RO   | 250.00 |
| 20161122:20170131 | UN     | APP  | A4  | RO   | 450.00 |
| 20161122:20170131 | UN     | APP  | A6  | RO   | 650.00 |
