pobsd-parser

pobsd-parser is a parsing library for parsing the PlayOnBSD Database.

This library provides:

• A Parser struct handling the parsing
• A ParsingMode enum to choose between a strict or a relax parsing mode
• A ParserResult struct to handle parsing with and without error
• A Game struct representing a game of a database

Examples

Here is a first example loading a file in relaxed mode (by default).

extern crate pobsd_parser;
use pobsd_parser::{Parser, ParserResult};
// Create a parser
let parser = Parser::default();
// Load the database
let parser_result = parser.load_from_file("/path/to/games.db")
       .expect("Problem trying to open the file");
let games = match parser_result {
       ParserResult::WithoutError(games) => games,
       ParserResult::WithError(games, _) => games,
};

The parser can also use a strict mode in which it will stop when encountering a parsing error and returning the games it has processed.

extern crate pobsd_parser;
use pobsd_parser::{Parser, ParserResult, ParsingMode};

// Create a paser in strict mode
let parser = Parser::new(ParsingMode::Strict);
// Load the database
let parser_result = parser.load_from_file("/path/to/games.db")
       .expect("Problem trying to open the file");
let games = match parser_result {
    ParserResult::WithoutError(games) => games,
    ParserResult::WithError(games, _) => games,
};

The parser can also load from a &str or a String.

extern crate pobsd_parser;
use pobsd_parser::{Parser, ParserResult, ParsingMode};
