Struct BundleBuilder 

pub struct BundleBuilder { /* private fields */ }

Builds a .pkg bundle file.

Implementations

impl BundleBuilder

pub fn new() -> Self

pub fn add_section(&mut self, kind: SectionKind, path: String, data: Vec<u8>)

pub fn add_manifest(&mut self, manifest: &Manifest) -> Result<()>

pub fn add_crate_file(&mut self, name: &str, version: &str, data: Vec<u8>)

pub fn add_index_entry(&mut self, name: &str, data: Vec<u8>)

pub fn add_rustup_file(&mut self, target: &str, filename: &str, data: Vec<u8>)

pub fn add_dist_file(&mut self, relative_path: &str, data: Vec<u8>)

pub fn add_config(&mut self, config_toml: &str)

pub fn add_config_file(&mut self, filename: &str, data: Vec<u8>)

Add a named config file under the config/ prefix. Used by snapshot exports to bundle multiple files (e.g. frostmirror.toml, depends.toml) so the importer can place them back into the config dir.

pub fn write_to_file(&self, path: &Path) -> Result<()>

Write the bundle to a file, compressed with brotli.

Bundle format (before brotli compression):

• 8 bytes: magic “FMPKG\x00\x01\x00”
• 4 bytes: number of sections (u32 LE)
• For each section in the header table:
  • 4 bytes: path length (u32 LE)
  • N bytes: path (UTF-8)
  • 8 bytes: data offset (u64 LE)
  • 8 bytes: data length (u64 LE)
• Raw section data concatenated
