Enum ConcurrencyControlType 

#[non_exhaustive]
pub enum ConcurrencyControlType {
    Unlimited,
    Task,
    Argument,
    None,
}

Concurrency control strategy for a task.

Determines how concurrent invocations of the same task are handled.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Unlimited

No concurrency restrictions

Task

Only one invocation per (task_id, key_args) at a time

Argument

Only one invocation per exact argument set

None

No concurrent invocations allowed at all

Trait Implementations

impl Clone for ConcurrencyControlType

fn clone(&self) -> ConcurrencyControlType

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ConcurrencyControlType

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

Formats the value using the given formatter.

impl Default for ConcurrencyControlType

fn default() -> Self

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for ConcurrencyControlType

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for ConcurrencyControlType

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

Formats the value using the given formatter.

impl FromStr for ConcurrencyControlType

type Err = String

The associated error which can be returned from parsing.

fn from_str(s: &str) -> Result<Self, Self::Err>

Parses a string s to return a value of this type.

impl PartialEq for ConcurrencyControlType

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

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

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Copy for ConcurrencyControlType
