Struct garage_model::s3::version_table::Version

pub struct Version {
    pub uuid: Uuid,
    pub deleted: Bool,
    pub blocks: Map<VersionBlockKey, VersionBlock>,
    pub backlink: VersionBacklink,
}

A version of an object

Fields

uuid: Uuid

UUID of the version, used as partition key

deleted: Bool

Is this version deleted

blocks: Map<VersionBlockKey, VersionBlock>

list of blocks of data composing the version

backlink: VersionBacklink

Implementations

impl Version

pub fn new(uuid: Uuid, backlink: VersionBacklink, deleted: bool) -> Self

pub fn has_part_number(&self, part_number: u64) -> bool

pub fn n_parts(&self) -> Result<u64, Error>

Trait Implementations

impl Clone for Version

fn clone(&self) -> Version

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Crdt for Version

fn merge(&mut self, other: &Self)

Merge the two datastructures according to the CRDT rules. self is modified to contain the merged CRDT value. other is not modified.

impl Debug for Version

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Version

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Entry<FixedBytes32, EmptyKey> for Version

fn partition_key(&self) -> &Uuid

Get the key used to partition

fn sort_key(&self) -> &EmptyKey

Get the key used to sort

fn is_tombstone(&self) -> bool

Is the entry a tombstone? Default implementation always return false

impl Migrate for Version

const VERSION_MARKER: &'static [u8] = b"G09s3v"

A sequence of bytes to add at the beginning of the serialized string, to identify that the data is of this version.

type Previous = Version

The previous version of this data type, from which items of this version can be migrated.

fn migrate(old: Version) -> Version

The migration function that transforms a value decoded in the old format to an up-to-date value.

fn decode(bytes: &[u8]) -> Option<Self>

Decode an encoded version of this type, going through a migration if necessary.

fn encode(&self) -> Result<Vec<u8>, Error>

Encode this type with optional version marker

impl PartialEq for Version

fn eq(&self, other: &Version) -> 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 Serialize for Version

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Eq for Version

impl StructuralPartialEq for Version
