Module libpobsd::parsing

source ·
Expand description

Provides a simplistic Parser that converts the PlayOnBSD Database (either provided as a string or as a file) into a vector of Games.

§Examples

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

use libpobsd::{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.

use libpobsd::{Parser, ParserResult, ParsingMode};

// Create a parser 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.

use libpobsd::{Parser, ParserResult, ParsingMode, Game};

let parser = Parser::default();
let games = match parser.load_from_string(games) {
    ParserResult::WithoutError(games) => games,
    // Should not panic since the data are fine
    ParserResult::WithError(_, _) => panic!(),
};
let game1: &Game = games.get(1).unwrap();
assert_eq!(Some(String::from("godot")), game1.engine);

Structs§

  • Parses the PlayOnBSD database provided as a &str or from a file and returns a ParserResult holding a vector of Game contained in the PlayOnBSD database.

Enums§

  • Represents the result of the parsing. When in strict mode, only the games parsed before a parsing error occurred will be returned. In relaxed mode, the parser will do its best to continue parsing games.
  • Represents the two parsing modes supported by Parser.
