Struct GenDiskBuilder

pub struct GenDiskBuilder { /* private fields */ }

A builder for GenDisk.

Use this struct to configure and add new GenDisk to the VFS.

Implementations

impl GenDiskBuilder

pub fn new() -> Self

Create a new instance.

pub fn rotational(self, rotational: bool) -> Self

Set the rotational media attribute for the device to be built.

pub fn logical_block_size(self, block_size: u32) -> Result<Self>

Set the logical block size of the device to be built.

This method will check that block size is a power of two and between 512 and 4096. If not, an error is returned and the block size is not set.

This is the smallest unit the storage device can address. It is typically 4096 bytes.

pub fn physical_block_size(self, block_size: u32) -> Result<Self>

Set the physical block size of the device to be built.

This method will check that block size is a power of two and between 512 and 4096. If not, an error is returned and the block size is not set.

This is the smallest unit a physical storage device can write atomically. It is usually the same as the logical block size but may be bigger. One example is SATA drives with 4096 byte physical block size that expose a 512 byte logical block size to the operating system.

pub fn capacity_sectors(self, capacity: u64) -> Self

Set the capacity of the device to be built, in sectors (512 bytes).

pub fn build<T: Operations>( self, name: Arguments<'_>, tagset: Arc<TagSet<T>>, ) -> Result<GenDisk<T>>

Build a new GenDisk and add it to the VFS.

Trait Implementations

impl Default for GenDiskBuilder

fn default() -> Self

Returns the “default value” for a type.
