Struct VersionedTask 

pub struct VersionedTask {
    pub task: Task,
    pub version: u64,
}

A task paired with its storage version — the optimistic-concurrency token.

The version is a monotonic counter the storage adapter bumps on every successful mutation of the task. A caller reads a task and its version, then passes that version back on a conditional update (AsyncTaskVersioning::update_status_checked); if another writer advanced the task in between, the update fails with A2AError::VersionConflict instead of silently clobbering it.

Fields

task: Task

The task at this version.

version: u64

The storage version this snapshot was read or written at.

Implementations

impl VersionedTask

pub fn new(task: Task, version: u64) -> Self

Pair a task with a version.

Trait Implementations

impl Clone for VersionedTask

fn clone(&self) -> VersionedTask

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for VersionedTask

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

Formats the value using the given formatter.

impl PartialEq for VersionedTask

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