Implementations

impl Manifest

pub fn parse(bytes: &[u8]) -> Result<Self>

Deserialize a manifest and validate its platform, digests and filenames.

pub fn validate(&self) -> Result<()>

Validate public fields even when constructed directly or deserialized.

pub fn gpu_target(&self) -> Result<Target>

Parse the GPU architecture from the supported host platform identifier.

pub fn verify(&self, directory: &Path) -> Result<()>

Validate the manifest and verify every expected regular file in a directory.

pub fn install(&self, archive: &Path, root: &Path) -> Result<PathBuf>

Verify the compressed archive before unpacking. Reject links, paths and undeclared files, then publish the entire directory with one rename.
