Struct L2Entry

pub struct L2Entry(/* private fields */);

Implementations

impl L2Entry

pub fn cluster_offset(&self) -> u64

pub fn is_compressed(&self) -> bool

pub fn is_copied(&self) -> bool

pub fn is_zero(&self) -> bool

pub fn reserved_bits(&self) -> u64

pub fn compressed_descriptor(&self) -> u64

pub fn compressed_range(&self, cluster_bits: u32) -> Option<(u64, usize)>

If this entry is compressed, return the start host offset and upper limit on the compressed number of bytes

pub fn allocation(&self, cluster_bits: u32) -> Option<(u64, usize)>

If this entry is allocated, return the host cluster offset and the number of clusters it references; otherwise return None.

pub fn into_mapping( self, info: &Qcow2Info, guest_addr: &SplitGuestOffset, ) -> Mapping

Convert to mapping

guest_addr is only used for backing offset

pub fn from_mapping(value: Mapping, cluster_bits: u32) -> Self
