Struct driver_block::ramdisk::RamDisk

pub struct RamDisk { /* private fields */ }

Available on crate feature ramdisk only.

A RAM disk that stores data in a vector.

Implementations

impl RamDisk

pub fn new(size_hint: usize) -> Self

Creates a new RAM disk with the given size hint.

The actual size of the RAM disk will be aligned upwards to the block size (512 bytes).

pub fn from(buf: &[u8]) -> Self

Creates a new RAM disk from the exiting data.

The actual size of the RAM disk will be aligned upwards to the block size (512 bytes).

pub const fn size(&self) -> usize

Returns the size of the RAM disk in bytes.
