Enum IdReusePolicy 

#[repr(i32)]
pub enum IdReusePolicy {
    Unspecified = 0,
    AllowIfPreviousExistsAbnormally = 1,
    AllowIfNoRunning = 2,
    DisallowReuse = 3,
    AllowTerminateIfRunning = 4,
}

Decides whether StartFlow may start a new run for a Flow ID that already has a run. Dex checks the latest run only. A Flow ID without runs always starts. A retry of the latest run’s start request skips this policy; see StartFlowRequest.request_id.

Variants

Unspecified = 0

Same as ID_REUSE_POLICY_DISALLOW_REUSE.

AllowIfPreviousExistsAbnormally = 1

Starts a new run when the latest run closed as FAILED, CANCELED, or TERMINATED. Rejects the start when the latest run is RUNNING or COMPLETED. A Flow timeout closes a run as FAILED or CANCELED under FAIL or CANCEL; under HANDLER, the handler decides.

AllowIfNoRunning = 2

Starts a new run when the latest run is closed, whatever its status.

DisallowReuse = 3

Rejects the start whenever the Flow ID has a run.

AllowTerminateIfRunning = 4

Terminates a running latest run, then starts a new run. Never rejects a new request.

Implementations

impl IdReusePolicy

pub const fn is_valid(value: i32) -> bool

Returns true if value is a variant of IdReusePolicy.

pub fn from_i32(value: i32) -> Option<IdReusePolicy>

👎Deprecated:

Use the TryFrom<i32> implementation instead

Converts an i32 to a IdReusePolicy, or None if value is not a valid variant.

impl IdReusePolicy

pub fn as_str_name(&self) -> &'static str

String value of the enum field names used in the ProtoBuf definition.

The values are not transformed in any way and thus are considered stable (if the ProtoBuf definition does not change) and safe for programmatic use.

pub fn from_str_name(value: &str) -> Option<Self>

Creates an enum from field names used in the ProtoBuf definition.

Trait Implementations

impl Clone for IdReusePolicy

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for IdReusePolicy

impl Debug for IdReusePolicy

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

Formats the value using the given formatter.

impl Default for IdReusePolicy

fn default() -> IdReusePolicy

Returns the “default value” for a type.

impl Eq for IdReusePolicy

impl From<IdReusePolicy> for i32

fn from(value: IdReusePolicy) -> i32

Converts to this type from the input type.

impl Hash for IdReusePolicy

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Ord for IdReusePolicy

fn cmp(&self, other: &Self) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

fn clamp_to<R>(self, range: R) -> Self

where Self: Sized, R: ClampBounds<Self>,

🔬This is a nightly-only experimental API. (clamp_to)

Restrict a value to a certain range.

impl PartialEq for IdReusePolicy

fn eq(&self, other: &Self) -> bool

Equality operator ==.

fn ne(&self, other: &Rhs) -> bool

Inequality operator !=.

impl PartialOrd for IdReusePolicy

fn partial_cmp(&self, other: &Self) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Rhs) -> bool

Tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

Tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

Tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

Tests greater than or equal to (for self and other) and is used by the >= operator.

impl StructuralPartialEq for IdReusePolicy

impl TryFrom<i32> for IdReusePolicy

type Error = UnknownEnumValue

The type returned in the event of a conversion error.

fn try_from(value: i32) -> Result<IdReusePolicy, UnknownEnumValue>

Performs the conversion.
