Trait Implementations

impl AsRef<[u8]> for VolumeStateKey

fn as_ref(&self) -> &[u8]

Converts this type into a shared reference of the (usually inferred) input type.

impl Clone for VolumeStateKey

fn clone(&self) -> VolumeStateKey

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for VolumeStateKey

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

Formats the value using the given formatter.

impl From<VolumeStateKey> for Slice

fn from(key: VolumeStateKey) -> Slice

Converts to this type from the input type.

impl IntoBytes for VolumeStateKey

where VolumeId: IntoBytes, VolumeStateTag: IntoBytes, (): PaddingFree<Self, { _ }>,

fn as_bytes(&self) -> &[u8]

where Self: Immutable,

Gets the bytes of this value.

fn write_to(&self, dst: &mut [u8]) -> Result<(), SizeError<&Self, &mut [u8]>>

where Self: Immutable,

Writes a copy of self to dst.

fn write_to_prefix( &self, dst: &mut [u8], ) -> Result<(), SizeError<&Self, &mut [u8]>>

where Self: Immutable,

Writes a copy of self to the prefix of dst.

fn write_to_suffix( &self, dst: &mut [u8], ) -> Result<(), SizeError<&Self, &mut [u8]>>

where Self: Immutable,

Writes a copy of self to the suffix of dst.

impl KnownLayout for VolumeStateKey

where VolumeStateTag: KnownLayout,

type PointerMetadata = <VolumeStateTag as KnownLayout>::PointerMetadata

The type of metadata stored in a pointer to Self.

impl PartialEq for VolumeStateKey

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