Enum CorrelationKind 

#[repr(i32)]
pub enum CorrelationKind {
    None = 0,
    Request = 1,
    Response = 2,
}

Request/response correlation discriminator.

Variants

None = 0

Fire-and-forget — no correlation header.

Request = 1

The envelope opens a new request. The wire_req_id is the sender’s token; the receiver echoes it back inside a RESPONSE.

Response = 2

The envelope answers a prior REQUEST. The wire_req_id matches the original request’s token.

Implementations

impl CorrelationKind

pub fn is_valid(value: i32) -> bool

Returns true if value is a variant of CorrelationKind.

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

👎Deprecated:

Use the TryFrom<i32> implementation instead

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

impl CorrelationKind

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<CorrelationKind>

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

Trait Implementations

impl Clone for CorrelationKind

fn clone(&self) -> CorrelationKind

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for CorrelationKind

impl Debug for CorrelationKind

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

Formats the value using the given formatter.

impl Default for CorrelationKind

fn default() -> CorrelationKind

Returns the “default value” for a type.

impl Eq for CorrelationKind

impl Hash for CorrelationKind

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 CorrelationKind

fn cmp(&self, other: &CorrelationKind) -> 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 CorrelationKind

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

fn partial_cmp(&self, other: &CorrelationKind) -> 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 CorrelationKind

impl TryFrom<i32> for CorrelationKind

type Error = UnknownEnumValue

The type returned in the event of a conversion error.

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

Performs the conversion.
