Struct DeviceAllocation 

pub struct DeviceAllocation {
    pub devid: u64,
    pub flags: BlockGroupFlags,
    pub bytes: u64,
}

Physical allocation of one block-group profile on one device, as read from the chunk tree.

bytes is the sum of stripe_len over all chunk stripes that land on devid and share the same flags. This is the physical space the device contributes to that profile, not the logical (usable) space.

Fields

devid: u64

btrfs device ID.

flags: BlockGroupFlags

Combined block-group type and profile flags, e.g. BlockGroupFlags::DATA | BlockGroupFlags::RAID1.

bytes: u64

Physical bytes allocated on this device for chunks with these flags.

Trait Implementations

impl Clone for DeviceAllocation

fn clone(&self) -> DeviceAllocation

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for DeviceAllocation

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for DeviceAllocation

fn eq(&self, other: &DeviceAllocation) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
