Struct BundleWriter 

pub struct BundleWriter;

A build-tool-facing writer for the explicit final assembly boundary.

Implementations

impl BundleWriter

pub fn write( root: impl AsRef<Path>, manifest: &ManifestDocument, assets: &BTreeMap<AssetId, Vec<u8>>, binaries: &BTreeMap<BundlePath, PathBuf>, ) -> Result<RuntimeBundle, BundleError>

Write one bundle: the manifest, the assets, and the binaries.

The bundle is assembled in a private sibling directory and only then renamed onto its final name, so the target is either absent or a complete bundle.

binaries maps the bundle-relative destination - bin/brain, bin/<service-id>, bin/<component-type> - to the executable to copy there. Nothing is hashed and nothing is recorded: the launcher derives the executable from the id it is launching, and integrity is the archive’s job.

Errors

Returns BundleError::TargetExists when root already exists, BundleError::NotExecutable or BundleError::UnsupportedEntry when a supplied binary is not a runnable file, and BundleError::ReadFile for any other I/O failure. A failed write leaves no staging directory behind.
