Fields

total_bytes: u64

The number of data bytes which may be stored in a filesystem. This does not count metadata or other filesystem overhead like block rounding.

used_bytes: u64

The number of data bytes which are in use by the filesystem. This does not count metadata or other filesystem overhead like block rounding.

total_nodes: u64

The number of nodes which may be stored in the filesystem.

used_nodes: u64

The number of nodes used by the filesystem.

free_shared_pool_bytes: u64

The amount of additional space which may be allocated from the underlying volume manager. If unsupported or there is no space for the filesystem to grow, this will be zero.

fs_id: u64

A unique identifier for this filesystem instance. Will not be preserved across reboots.

Implementors should create a kernel object (normally an event) and use its koid for the filesystem ID. This koid guarantees uniqueness in the system.

block_size: u32

The size in bytes of a single filesystem block.

max_filename_size: u32

The maximum length of a filesystem name.

fs_type: u32

A unique identifier for the type of the underlying filesystem.

padding: u32

name: [i8; 32]

Trait Implementations

impl Clone for FilesystemInfo

fn clone(&self) -> FilesystemInfo

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for FilesystemInfo

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

Formats the value using the given formatter.

impl<D: ResourceDialect> Decode<FilesystemInfo, D> for FilesystemInfo

fn new_empty() -> Self

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<()>

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

impl<D: ResourceDialect> Encode<FilesystemInfo, D> for &FilesystemInfo

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

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

impl<D: ResourceDialect, T0: Encode<u64, D>, T1: Encode<u64, D>, T2: Encode<u64, D>, T3: Encode<u64, D>, T4: Encode<u64, D>, T5: Encode<u64, D>, T6: Encode<u32, D>, T7: Encode<u32, D>, T8: Encode<u32, D>, T9: Encode<u32, D>, T10: Encode<Array<i8, 32>, D>> Encode<FilesystemInfo, D> for (T0, T1, T2, T3, T4, T5, T6, T7, T8, T9, T10)

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

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

impl Hash for FilesystemInfo

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

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 FilesystemInfo

fn cmp(&self, other: &FilesystemInfo) -> 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 + PartialOrd,

Restrict a value to a certain interval.

impl PartialEq for FilesystemInfo

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

This method tests for self and other values to be equal, and is used by ==.

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

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

impl PartialOrd for FilesystemInfo

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

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

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

This method tests less than (for self and other) and is used by the < operator.

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

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

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

This method tests greater than (for self and other) and is used by the > operator.

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

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

impl TypeMarker for FilesystemInfo

type Owned = FilesystemInfo

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 FilesystemInfo

type Borrowed<'a> = &'a FilesystemInfo

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: &<Self as TypeMarker>::Owned) -> Self::Borrowed<'_>

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