//! Stream label extraction from BD-J disc files.
|
|
//!
|
|
//! Each parser module represents one BD-J authoring framework.
|
|
//! To add a new format:
|
|
//! 1. Create `src/labels/myformat.rs`
|
|
//! 2. Implement `pub fn detect(udf: &UdfFs) -> bool`
|
|
//! 3. Implement `pub fn parse(reader: &mut dyn SectorSource, udf: &UdfFs) -> Option<ParseResult>`
|
|
//! (set [`ParseResult::confidence`]; it drives parser selection on
|
|
//! a tie)
|
|
//! 4. Add `mod myformat;` below and one line to `PARSERS` array
