Struct docker_api::models::ObjectVersion

pub struct ObjectVersion {
    pub index: Option<u64>,
}

The version number of the object such as node, service, etc. This is needed to avoid conflicting writes. The client must send the version number along with the modified specification when updating these objects.

This approach ensures safe concurrency and determinism in that the change on the object may not be applied if the version number has changed from the last read. In other words, if two update requests specify the same base version, only one of the requests can succeed. As a result, two separate update requests that happen at the same time will not unintentionally overwrite each other.

Trait Implementations

impl Clone for ObjectVersion

fn clone(&self) -> ObjectVersion

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for ObjectVersion

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for ObjectVersion

fn deserialize<__D>( __deserializer: __D ) -> Result<ObjectVersion, <__D as Deserializer<'de>>::Error>where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq<ObjectVersion> for ObjectVersion

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

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

Serialize this value into the given Serde serializer.
