Enum AssetSource 

pub enum AssetSource {
    Path(PathBuf),
    Packed {
        offset: u64,
        size: u64,
        uncompressed_size: u64,
        compression: CompressionKind,
    },
}

Represents the physical source of an asset’s data.

This enum allows the asset system to transparently handle assets from two different contexts:

• In editor/development mode, assets are loaded directly from loose files on disk (Path).
• In release/standalone mode, assets are loaded from an optimized packfile (Packed).

Pack format version: v2 added per-entry compression (compression, uncompressed_size). v1 packs (without these fields) are no longer supported on the read side; the loader bails on the header version check before reaching this struct.

Variants

Path(PathBuf)

The asset is a loose file on disk. The PathBuf points to the file.

Packed

The asset is located within a packfile.

Fields

offset: u64

Byte offset from the start of the asset region (i.e. after the 24-byte header) in data.pack.

size: u64

Number of bytes to read from the pack at offset — the on-disk size, possibly compressed.

uncompressed_size: u64

Size of the asset after decompression. Equals size when compression == CompressionKind::None.

compression: CompressionKind

Compression scheme applied to the bytes between offset and offset + size.
