Struct AssetPack 

pub struct AssetPack { /* private fields */ }

A bundle of multiple asset files stored in a single archive.

Format

[4 bytes magic "PACK"]
[4 bytes version = 1 as little-endian u32]
[4 bytes entry_count as little-endian u32]
For each entry:
  [4 bytes path_len as little-endian u32]
  [path_len bytes UTF-8 path]
  [8 bytes data_offset as little-endian u64]
  [8 bytes data_length as little-endian u64]
[raw concatenated asset bytes]

The data section immediately follows the directory.

Implementations

impl AssetPack

pub fn from_bytes( name: impl Into<String>, bytes: Vec<u8>, ) -> Result<Self, String>

Parse an asset pack from raw bytes.

Returns Err if the bytes do not match the expected format.

pub fn build(name: impl Into<String>, files: &[(&str, &[u8])]) -> Vec<u8>

Build a pack from a map of virtual_path → bytes.

pub fn read(&self, virtual_path: &str) -> Option<&[u8]>

Read a virtual file from the pack by its path.

pub fn paths(&self) -> impl Iterator<Item = &str>

List all virtual paths in this pack.

pub fn name(&self) -> &str

The name of this pack.

pub fn entry_count(&self) -> usize

Number of entries in this pack.
