Fields

protocols: Option<NodeProtocolKinds>

Describes the kinds of representations supported by the node. Note: This is not the result of the connection-time negotiation, which is conveyed via representation.

abilities: Option<Operations>

Describes the kinds of operations supported by the node. Note: This is distinct from the rights used at connection time.

content_size: Option<u64>

Node size, in bytes.

storage_size: Option<u64>

Space needed to store the node (possibly larger than size), in bytes.

link_count: Option<u64>

Number of hard links to the node. It must be at least one.

id: Option<u64>

An ID for the node. See Id. This id should be unique among all entries of a directory.

change_time: Option<u64>

Time of last change to the metadata in nanoseconds since the Unix epoch, UTC.

options: Option<VerificationOptions>

Contains the verification options for verity-enabled files.

root_hash: Option<Vec<u8>>

The root hash for the file. Not all filesystems support this across all files.

verity_enabled: Option<bool>

True if this file is verity-enabled.

Trait Implementations

impl Clone for ImmutableNodeAttributes

fn clone(&self) -> ImmutableNodeAttributes

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for ImmutableNodeAttributes

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

Formats the value using the given formatter.

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

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 Default for ImmutableNodeAttributes

fn default() -> ImmutableNodeAttributes

Returns the “default value” for a type.

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

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 PartialEq for ImmutableNodeAttributes

fn eq(&self, other: &ImmutableNodeAttributes) -> 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 TypeMarker for ImmutableNodeAttributes

type Owned = ImmutableNodeAttributes

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 ImmutableNodeAttributes

type Borrowed<'a> = &'a ImmutableNodeAttributes

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.
