Crate bms_table 

BMS difficulty table parsing

Provides building a complete BMS difficulty table data structure from header JSON and chart data JSON, covering the header, courses, trophies, and chart items. Also includes HTML parsing (via htmlparser) for extracting the bmstable header URL from a page.

Features

• Parse header JSON into BmsTableHeader, preserving unrecognized fields in extra for forward compatibility;
• Parse chart data into BmsTableData, supporting a plain array of ChartItem structure;
• Course md5/sha256 shorthand lists are preserved as independent fields; use CourseInfo::all_charts for a merged view;
• Extract the header JSON URL from HTML <meta name="bmstable"> (zero-copy, returns &str).

Usage

use bms_table::{BmsTable, BmsTableHeader, BmsTableData};

let header_json = r#"{ "name": "Test", "symbol": "t", "data_url": "charts.json", "course": [], "level_order": [] }"#;
let data_json = r#"[]"#;
let header: BmsTableHeader = serde_json::from_str(header_json)?;
let data: BmsTableData = serde_json::from_str(data_json)?;
let table = BmsTable::new(header, data);
assert!(table.header.course.flatten().is_empty());
