embed-resources (Work in Progress)

embed-resources is a Rust crate built on top of embed-bytes that extends its functionality to handle multiple resource types: local files, URLs, and in-memory data. It also supports optional Gzipped compression for reduced storage size.

Unlike embed-bytes, which directly embeds assets, embed-resources simplifies managing mixed resources by organizing them in a virtual "container." Resources are automatically converted into .bin files, and a Rust source file is generated to embed them using include_bytes!.

Key Features:

• Multi-Type Resource Support: Embed local files, fetch remote data, or embed arbitrary in-memory data.
• Optional Compression: Compress resources with Gzipped encoding during the build process.
• Unified Management: Organize resources into a container with minimal setup while benefiting from zero-cost runtime embedding.

Example Usage:

In build.rs:

use embed_resources::{Resource, ResourceContainer};
use std::path::Path;

fn main() -> std::io::Result<()> {
    let mut container = ResourceContainer::new(Path::new("embed"));

    container.add_resource("local_file", Resource::File("assets/file.txt".to_string()), true);
    container.add_resource("remote_data", Resource::Url("https://example.com/data.bin".to_string()), true);
    container.add_resource("in_memory_data", Resource::Data(bytes::Bytes::from("Hello, world!")), true);

    container.embed_all()?;

    Ok(())
}

This creates .bin files and a Rust source file in the embed/ directory, ready to use with include_bytes!.
