Struct FvmInstance

pub struct FvmInstance { /* private fields */ }

This structs holds processes of component manager, isolated-devmgr and the fvm driver.

NOTE: The order of fields in this struct is important. Destruction happens top-down. Test must be destroyed last.

Implementations

impl FvmInstance

pub async fn new( init: bool, vmo: &Vmo, fvm_slice_size: u64, ramdisk_block_size: u64, ) -> Self

Start an isolated FVM driver against the given VMO. If init is true, initialize the VMO with FVM layout first.

pub async fn new_volume( &mut self, name: &str, type_guid: &Guid, initial_volume_size: Option<u64>, ) -> Guid

Create a new FVM volume with the given name and type GUID. Returns the instance GUID used to uniquely identify this volume.

pub async fn free_space(&self) -> u64

Returns the number of bytes the FVM partition has available.

pub fn ramdisk_get_dir(&self) -> Option<&DirectoryProxy>

Returns a reference to the ramdisk DirectoryProxy.

pub async fn shutdown(self)

Shuts down the FVM instance and ramdisk that’s hosting it.
