Struct MetadataRevision 

pub struct MetadataRevision(/* private fields */);

Opaque equality/precondition token for metadata state.

Implementations

impl MetadataRevision

pub fn new(value: impl Into<Vec<u8>>) -> Result<Self>

Creates a non-empty opaque revision token.

Errors

Returns an error when validation fails or an underlying backend, store, or platform operation fails.

pub fn from_slice(value: &[u8]) -> Result<Self>

Copies a non-empty opaque revision token from a byte slice.

Errors

Returns an error when validation fails or an underlying backend, store, or platform operation fails.

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

Returns the opaque revision bytes.

pub fn into_bytes(self) -> Vec<u8>

Consumes the revision and returns its opaque bytes.

Trait Implementations

impl Clone for MetadataRevision

fn clone(&self) -> MetadataRevision

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for MetadataRevision

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

Formats the value using the given formatter.

impl Hash for MetadataRevision

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 PartialEq for MetadataRevision

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