disk_backend_resources::layer

Struct RamDiskLayerHandle

Source 
pub struct RamDiskLayerHandle {
    pub len: Option<u64>,
}
Expand description

RAM disk layer handle.

FUTURE: allocate shared memory here so that the disk can be migrated between processes.

Fields§

§len: Option<u64>

The size of the layer. If None, the layer will be the same size as the lower disk.
