Enum ProcessingKey 

#[repr(i32)]
pub enum ProcessingKey {
    RoutingKey = 0,
    Priority = 1,
    Timeout = 2,
    NrOfResults = 3,
}

An enumeration of possible keys for processing instructions.

Variants

RoutingKey = 0

key indicating that the attached value should be used for consistent routing.

Priority = 1

key indicating that the attached value indicates relative priority of this message.

Timeout = 2

key indicating that the accompanied message has a finite validity. The attached value contains the number of milliseconds.

NrOfResults = 3

key indicating that the requester expects at most the given number of results from this message. Use -1 for unlimited.

Implementations

impl ProcessingKey

pub fn is_valid(value: i32) -> bool

Returns true if value is a variant of ProcessingKey.

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

👎Deprecated: Use the TryFrom<i32> implementation instead

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

impl ProcessingKey

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<ProcessingKey>

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

Trait Implementations

impl Clone for ProcessingKey

fn clone(&self) -> ProcessingKey

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ProcessingKey

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

Formats the value using the given formatter.

impl Default for ProcessingKey

fn default() -> ProcessingKey

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for ProcessingKey

fn deserialize<__D>( __deserializer: __D, ) -> Result<ProcessingKey, <__D as Deserializer<'de>>::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Hash for ProcessingKey

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

where __H: Hasher,

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 ProcessingKey

fn cmp(&self, other: &ProcessingKey) -> 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.

impl PartialEq for ProcessingKey

fn eq(&self, other: &ProcessingKey) -> 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 PartialOrd for ProcessingKey

fn partial_cmp(&self, other: &ProcessingKey) -> 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 Serialize for ProcessingKey

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

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl TryFrom<i32> for ProcessingKey

type Error = DecodeError

The type returned in the event of a conversion error.

fn try_from(value: i32) -> Result<ProcessingKey, DecodeError>

Performs the conversion.
