revelo-reader

Input/reader registration layer for revelo — a fast, safe, pure-Rust port of MediaInfoLib for extracting technical and tag metadata from media files.

Part of the revelo project — see the project README for the full picture.

What it does

Before a media file reaches the format parsers, MediaInfoLib registers the source type through which the bytes arrive — filesystem path, directory, HTTP stream, or MMS URL. revelo-reader ports that reader-registration step: each function receives a mutable FileAnalyze context, ensures a General stream exists, and writes the Reader field that downstream parsers can inspect to adapt their behaviour.

Public API

Every function returns bool (true on success), matching the reader-dispatch contract used by revelo-core.

Usage

Add the dependency:

[dependencies]
revelo-reader = "0.4"
revelo-core   = "0.4"

Register a reader before handing the context to the format parsers:

use revelo_core::FileAnalyze;
use revelo_reader::parse_file_reader;

let mut fa = FileAnalyze::new(&[]);
parse_file_reader(&mut fa);
// fa's General stream now has Reader = "File".
// Pass `fa` to the appropriate format parser next.

For network sources, swap in the matching function:

use revelo_core::FileAnalyze;
use revelo_reader::{parse_http_reader, parse_mms_reader};

let mut fa = FileAnalyze::new(&[]);
parse_http_reader(&mut fa);   // Reader = "HTTP"

let mut fa2 = FileAnalyze::new(&[]);
parse_mms_reader(&mut fa2);   // Reader = "MMS"
