Struct BlockBuilder 

Source 
pub struct BlockBuilder {
    pub devices: VecDeque<Arc<Mutex<Block>>>,
}
Expand description

Wrapper for the collection that holds all the Block Devices

Fields§

§devices: VecDeque<Arc<Mutex<Block>>>

The list of block devices. There can be at most one root block device and it would be the first in the list.

Implementations§

Source§

impl BlockBuilder

Source

pub fn new() -> Self

Constructor for BlockDevices. It initializes an empty LinkedList.

Source

pub fn has_root_device(&self) -> bool

Specifies whether there is a root block device already present in the list.

Source

pub fn add_virtio_device(&mut self, block_device: Arc<Mutex<Block>>)

Inserts an existing block device.

Source

pub fn insert( &mut self, config: BlockDeviceConfig, has_pmem_root: bool, ) -> Result<(), DriveError>

Inserts a Block in the block devices list using the specified configuration. If a block with the same id already exists, it will overwrite it. Inserting a secondary root block device will fail.

Source

pub fn configs(&self) -> Vec<BlockDeviceConfig>

Returns a vec with the structures used to configure the devices.
