Fields

id: String

A unique ID of the task.

task: String

The name of the task.

lang: Option<String>

The programming language associated with the task.

root_id: Option<String>

The first task in the work-flow.

parent_id: Option<String>

The ID of the task that called this task within a work-flow.

group: Option<String>

The unique ID of the task’s group, if this task is a member.

meth: Option<String>

Currently unused but could be used in the future to specify class+method pairs.

shadow: Option<String>

Modifies the task name that is used in logs.

eta: Option<DateTime<Utc>>

A future time after which the task should be executed.

expires: Option<DateTime<Utc>>

A future time after which the task should be discarded if it hasn’t executed yet.

retries: Option<u32>

The number of times the task has been retried without success.

timelimit: (Option<u32>, Option<u32>)

A tuple specifying the hard and soft time limits, respectively.

Note that as of writing this, the Python celery docs actually have a typo where it says these are reversed.

argsrepr: Option<String>

A string representation of the positional arguments of the task.

kwargsrepr: Option<String>

A string representation of the keyword arguments of the task.

origin: Option<String>

A string representing the nodename of the process that produced the task.

Trait Implementations

impl Clone for MessageHeaders

fn clone(&self) -> MessageHeaders

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for MessageHeaders

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

Formats the value using the given formatter.

impl Default for MessageHeaders

fn default() -> MessageHeaders

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for MessageHeaders

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for MessageHeaders

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