Fields§

§path: PathBuf§read_only: bool§root: bool

Whether this disk should be the root device. Can only be set once. Only useful for adding specific command-line options.

§sparse: bool§direct: bool§block_size: u32§id: Option<[u8; 20]>§multiple_workers: bool

Experimental option to run multiple worker threads in parallel. If false, only single thread runs by default. Note this option is not effective for vhost-user blk device.

§async_executor: Option<ExecutorKind>

The async executor kind to simulate the block device with. This option takes precedence over the async executor kind specified by the subcommand’s option. If None, the default or the specified by the subcommand’s option would be used.

§packed_queue: bool§bootindex: Option<usize>

Specify the boot index for this device that the BIOS will use when attempting to boot from bootable devices. For example, if bootindex=2, then the BIOS will attempt to boot from the device right after booting from the device with bootindex=1 fails.

Implementations§

Open the specified disk file.

Trait Implementations§

Returns a copy of the value. Read more
Performs copy-assignment from source. Read more
Formats the value using the given formatter. Read more
Returns the “default value” for a type. Read more
Deserialize this value from the given Serde deserializer. Read more
Construct the type from a commandline value, returning an error string on failure.
This method tests for self and other values to be equal, and is used by ==.
This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
Serialize this value into the given Serde serializer. Read more

Auto Trait Implementations§

Blanket Implementations§

Gets the TypeId of self. Read more
Immutably borrows from an owned value. Read more
Mutably borrows from an owned value. Read more
Convert Box<dyn Trait> (where Trait: Downcast) to Box<dyn Any>. Box<dyn Any> can then be further downcast into Box<ConcreteType> where ConcreteType implements Trait.
Convert Rc<Trait> (where Trait: Downcast) to Rc<Any>. Rc<Any> can then be further downcast into Rc<ConcreteType> where ConcreteType implements Trait.
Convert &Trait (where Trait: Downcast) to &Any. This is needed since Rust cannot generate &Any’s vtable from &Trait’s.
Convert &mut Trait (where Trait: Downcast) to &Any. This is needed since Rust cannot generate &mut Any’s vtable from &mut Trait’s.
Convert Arc<Trait> (where Trait: Downcast) to Arc<Any>. Arc<Any> can then be further downcast into Arc<ConcreteType> where ConcreteType implements Trait.

Returns the argument unchanged.

Calls U::from(self).

That is, this conversion is whatever the implementation of From<T> for U chooses to do.

The resulting type after obtaining ownership.

Uses borrowed data to replace owned data, usually by cloning. Read more
The type returned in the event of a conversion error.
Performs the conversion.
