Struct PackLoader 

pub struct PackLoader { /* private fields */ }

Pack-based asset loader for release mode.

Reads assets from a .pack archive file by seeking to the recorded offset (shifted by PACK_HEADER_SIZE) and reading the specified number of bytes.

Implementations

impl PackLoader

pub fn new(pack_file: File) -> Result<Self>

Validates the leading header and returns a reader bound to pack_file.

Errors:

• file shorter than PACK_HEADER_SIZE or unreadable,
• magic doesn’t match PACK_MAGIC (file isn’t a Khora pack),
• format_version field doesn’t match PACK_FORMAT_VERSION (this runtime can’t read this pack — typically an older runtime reading a newer pack).

pub fn header(&self) -> &PackHeader

Returns a reference to the parsed header. Useful for diagnostics and for asserting header.asset_count == vfs.asset_count() at startup.

pub fn write_header( out: &mut impl Write, asset_count: u32, flags: u32, ) -> Result<()>

Writes a fresh 24-byte header at the start of out. Convenience helper for crate::asset::PackBuilder — keeps all the byte- layout knowledge in one module.
