Implementations

impl<R: IgvmLoaderRegister + GuestArch + 'static> IgvmLoader<R>

pub fn new(with_paravisor: bool, isolation_type: LoaderIsolationType) -> Self

fn generate_cryptographic_hash_of_shared_pages(&mut self) -> Vec<u8>

pub fn finalize(self, guest_svn: u32) -> Result<IgvmOutput>

Finalize the loader state, returning an IGVM file.

fn accept_new_range( &mut self, page_base: u64, page_count: u64, tag: &str, acceptance: BootPageAcceptance, ) -> Result<()>

Accept a new page range with a given acceptance into the map of accepted ranges.

fn imported_regions(&self) -> Vec<ImportedRegionDescriptor>

pub fn arch(&self) -> GuestArchKind

The guest architecture used by this loader.

pub fn confidential_debug(&self) -> bool

Returns true if this is an isolated guest with debug enabled, false otherwise.

pub fn loader(&mut self) -> IgvmVtlLoader<'_, R>

fn import_pages( &mut self, page_base: u64, page_count: u64, debug_tag: &str, acceptance: BootPageAcceptance, data: &[u8], ) -> Result<(), Error>
