Variants

Object

A generic, untyped object. This must come first and sort before all other keys for a given object because it’s also used as a tombstone and it needs to merge with all following keys.

Keys

Encryption keys for an object.

Attribute(u64, AttributeKeyV32)

An attribute associated with an object. It has a 64-bit ID.

Child

A child of a directory.

Fields

name: String

GraveyardEntry

A graveyard entry for an entire object.

Fields

object_id: u64

Project

Project ID info. This should only be attached to the volume’s root node. Used to address the configured limit and the usage tracking which are ordered after the project_id to provide locality of the two related values.

Fields

project_id: u64

property: ProjectPropertyV32

ExtendedAttribute

An extended attribute associated with an object. It stores the name used for the extended attribute, which has a maximum size of 255 bytes enforced by fuchsia.io.

Fields

name: Vec<u8>

GraveyardAttributeEntry

A graveyard entry for an attribute.

Fields

object_id: u64

attribute_id: u64

EncryptedCasefoldChild(EncryptedCasefoldChild)

A child of an encrypted directory. We store the filename in its encrypted form. hash_code is the hash of the casefolded human-readable name if a directory is also casefolded. In some legacy cases, this is also used in non-casefolded cases, and in some of those cases the hash code can be 0. Going forward, these cases are covered by EncryptedChild below.

LegacyCasefoldChild(CasefoldString)

Case-insensitive child (legacy).

EncryptedChild(EncryptedChild)

An encrypted child that does not use case folding.

CasefoldChild

A child of a directory that uses the casefold feature. (i.e. case insensitive, case preserving names)

Fields

hash_code: u32

name: String

Trait Implementations

impl Clone for ObjectKeyDataV54

fn clone(&self) -> ObjectKeyDataV54

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ObjectKeyDataV54

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for ObjectKeyDataV54

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl From<ObjectKeyDataV43> for ObjectKeyDataV54

fn from(item: ObjectKeyDataV43) -> Self

Converts to this type from the input type.

impl Hash for ObjectKeyDataV54

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 ObjectKeyDataV54

fn cmp(&self, other: &ObjectKeyDataV54) -> 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 ObjectKeyDataV54

fn eq(&self, other: &ObjectKeyDataV54) -> 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.

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.
