Fields

creation_time: Option<u64>

Time of creation in nanoseconds since the Unix epoch, UTC.

modification_time: Option<u64>

Time of last modification in nanoseconds since the Unix epoch, UTC.

mode: Option<u32>

POSIX compatibility attributes. Most filesystems will not support these. Those that do must simply store and retrieve them (e.g. as extended attributes) and not attempt to interpret them (e.g. by doing permission checks or handling device opens specially).

uid: Option<u32>

gid: Option<u32>

rdev: Option<u64>

access_time: Option<u64>

Time of last access in nanoseconds since the Unix epoch, UTC. Note that servers might not always update this if this is the only attribute being updated.

casefold: Option<bool>

Casefold (case-insensitive filename) support This attribute can only be changed on empty directories and will be inherited by any child directories that are subsequently created. The only filesystem to support this at the time of writing is Fxfs.

selinux_context: Option<SelinuxContext>

The value of the extended attribute “security.selinux” to be used in the context of SELinux implementations. The value can only be set or returned if it is MAX_SELINUX_CONTEXT_ATTRIBUTE_LEN characters or less to constrain the size of the response. If the value is not currently found on the node the response the field will not be included in the repsonse. If the value is found on the node but the server is not returning it here due to size or implementation, then it will return use_extended_attributes to indicate using the [’fuchsia.io/Node.GetExtendedAttribute`] to retreive it.

ZX_ERR_INVALID_ARGS will be returned if there is an attempt set this attribute with the use_extended_attributes member.

wrapping_key_id: Option<[u8; 16]>

Fscrypt support This attribute can only be changed on empty directories and will be inherited by any child directories that are subsequently created. This attribute can only be set once per directory. The wrapping_key_id set will be used to encrypt file contents and filenames for this directory and its children. The only filesystem to support this at the time of writing is Fxfs.

Trait Implementations

impl Clone for MutableNodeAttributes

fn clone(&self) -> MutableNodeAttributes

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for MutableNodeAttributes

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

Formats the value using the given formatter.

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

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 MutableNodeAttributes

fn default() -> MutableNodeAttributes

Returns the “default value” for a type.

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

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 MutableNodeAttributes

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

type Owned = MutableNodeAttributes

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 MutableNodeAttributes

type Borrowed<'a> = &'a MutableNodeAttributes

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.

impl Persistable for MutableNodeAttributes

impl StructuralPartialEq for MutableNodeAttributes
