#[repr(i16)]
pub enum TaskStatus {
    Pending = 1,
    Processing = 2,
    Completed = 3,
    Failed = 4,
    Cancelled = 5,

    DeadLetter = 7,
}

任务状态枚举

Variants

Pending = 1

待处理

Processing = 2

处理中

Completed = 3

已完成

Failed = 4

失败

Cancelled = 5

已取消

Scheduled = 6

已调度（定时任务）

DeadLetter = 7

Implementations

impl TaskStatus

pub fn from_i16(v: i16) -> Option<Self>

从 i16 值转换为 TaskStatus 枚举

pub fn to_i16(self) -> i16

将 TaskStatus 枚举转换为 i16 值

pub fn is_terminal(self) -> bool

判断是否为终态（不会再流转）

Trait Implementations

impl Clone for TaskStatus

fn clone(&self) -> TaskStatus

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for TaskStatus

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for TaskStatus

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for TaskStatus

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

impl Serialize for TaskStatus

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
