Struct VolumeManagerInfo

#[repr(C)]
pub struct VolumeManagerInfo {
    pub slice_size: u64,
    pub slice_count: u64,
    pub assigned_slice_count: u64,
    pub maximum_slice_count: u64,
    pub max_virtual_slice: u64,
}

VolumeManagerInfo describes the properties of the volume manager and not each individual volume.

Fields

slice_size: u64

Size of a single slice, in bytes.

slice_count: u64

Number of slices the volume manager is able use right now. This counts the allocated_slice_count plus the number of available slices.

assigned_slice_count: u64

Number of slices currently assigned to partitions.

maximum_slice_count: u64

The maximum capacity which the Volume Manager could grow to utilize if the partition containing the Volume Manager itself expands (i.e., the Volume Manager is initialized on a GPT partition that has extended beyond the originally allocated capacity). This value is the number of entries reserved in the volume manager header and is not related to the size of the physical device (which may be larger or smaller).

max_virtual_slice: u64

Largest value that can be used for a virtual slice number.

Trait Implementations

impl Clone for VolumeManagerInfo

fn clone(&self) -> VolumeManagerInfo

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for VolumeManagerInfo

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

Formats the value using the given formatter.

impl<D> Decode<VolumeManagerInfo, D> for VolumeManagerInfo

where D: ResourceDialect,

fn new_empty() -> VolumeManagerInfo

Creates a valid instance of Self. The specific value does not matter, since it will be overwritten by decode.

unsafe fn decode( &mut self, decoder: &mut Decoder<'_, D>, offset: usize, _depth: Depth, ) -> Result<(), Error>

Decodes an object of type T from the decoder’s buffers into self.

impl<D> Encode<VolumeManagerInfo, D> for &VolumeManagerInfo

where D: ResourceDialect,

unsafe fn encode( self, encoder: &mut Encoder<'_, D>, offset: usize, _depth: Depth, ) -> Result<(), Error>

Encodes the object into the encoder’s buffers. Any handles stored in the object are swapped for Handle::INVALID.

impl Hash for VolumeManagerInfo

fn hash<__H>(&self, state: &mut __H)

where __H: Hasher,

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Ord for VolumeManagerInfo

fn cmp(&self, other: &VolumeManagerInfo) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for VolumeManagerInfo

fn eq(&self, other: &VolumeManagerInfo) -> 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.

impl PartialOrd for VolumeManagerInfo

fn partial_cmp(&self, other: &VolumeManagerInfo) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.

impl TypeMarker for VolumeManagerInfo

type Owned = VolumeManagerInfo

The owned Rust type which this FIDL type decodes into.

fn inline_align(_context: Context) -> usize

Returns the minimum required alignment of the inline portion of the encoded object. It must be a (nonzero) power of two.

fn inline_size(_context: Context) -> usize

Returns the size of the inline portion of the encoded object, including padding for alignment. Must be a multiple of inline_align.

fn encode_is_copy() -> bool

Returns true if the memory layout of Self::Owned matches the FIDL wire format and encoding requires no validation. When true, we can optimize encoding arrays and vectors of Self::Owned to a single memcpy.

fn decode_is_copy() -> bool

Returns true if the memory layout of Self::Owned matches the FIDL wire format and decoding requires no validation. When true, we can optimize decoding arrays and vectors of Self::Owned to a single memcpy.

impl ValueTypeMarker for VolumeManagerInfo

type Borrowed<'a> = &'a VolumeManagerInfo

The Rust type to use for encoding. This is a particular Encode<Self> type cheaply obtainable from &Self::Owned. There are three cases:

fn borrow( value: &<VolumeManagerInfo as TypeMarker>::Owned, ) -> <VolumeManagerInfo as ValueTypeMarker>::Borrowed<'_>

Cheaply converts from &Self::Owned to Self::Borrowed.
