Variants

Fxfs(FxfsKey)

Fxfs’s default crypto (AES256GCM-SIV wrapped key using AES256XTS encryption) In: 16-byte wrapping_key_id + 48-byte wrapped key. Out: 32-byte unwrapped key.

Zxcrypt(Vec<u8>)

Zxcrypt (For use with FVM/Minfs only) In: 132-byte request blob. Out: 80-byte unwrapped key blob.

FscryptInoLblk32Dir(FscryptKeyIdentifierAndNonce)

Fscrypt INO_LBLK32 directory (For use with starnix only) In: 16-byte key_identifier + 16-byte UUID + 16-byte nonce. Out: 32-byte xts_key1, 32-byte xts_key2, 16-byte ino_hash, 16-byte dirhash.

FscryptInoLblk32File(FscryptKeyIdentifier)

Fscrypt INO_LBLK32 file (For use with starnix only) In: 16-byte key_identifier + 16-byte UUID. Out: 32-byte xts_key1, 32-byte xts_key2, 16-byte ino_hash.

DmDefaultKey(EmptyStruct)

Devicemapper DefaultKey (For use with starnix only) In: None. This is a singleton. wrapping_key_id should be set to 0. Out: 32-byte xts_key1, 32-byte xts_key2.

FscryptPerFile(FscryptKeyIdentifierAndNonce)

fscrypt default per-file encryption.

Implementations

impl WrappedKey

pub fn ordinal(&self) -> u64

pub fn unknown_variant_for_testing() -> WrappedKey

pub fn is_unknown(&self) -> bool

Trait Implementations

impl Clone for WrappedKey

fn clone(&self) -> WrappedKey

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for WrappedKey

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

Formats the value using the given formatter.

impl<D> Decode<WrappedKey, D> for WrappedKey

where D: ResourceDialect,

fn new_empty() -> WrappedKey

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<WrappedKey, D> for &WrappedKey

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 PartialEq for WrappedKey

fn eq(&self, other: &WrappedKey) -> 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 WrappedKey

type Owned = WrappedKey

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 WrappedKey

type Borrowed<'a> = &'a WrappedKey

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: &<WrappedKey as TypeMarker>::Owned, ) -> <WrappedKey as ValueTypeMarker>::Borrowed<'_>

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