Struct CorrelationId 

pub struct CorrelationId(/* private fields */);

A business correlation identifier for grouping related operations.

Correlation IDs are used to link operations that are related from a business perspective, even if they span multiple traces or occur at different times.

Implementations

impl CorrelationId

pub fn new() -> Self

Generate a new random correlation ID.

Examples

use hammerwork::tracing::CorrelationId;

let correlation_id = CorrelationId::new();
assert!(!correlation_id.to_string().is_empty());

pub fn from_string(id: impl Into<String>) -> Self

Create a correlation ID from an existing string.

Arguments

• id - The correlation identifier string

Examples

use hammerwork::tracing::CorrelationId;

let correlation_id = CorrelationId::from_string("order-12345");
assert_eq!(correlation_id.to_string(), "order-12345");

pub fn into_string(self) -> String

Get the correlation ID as a string.

pub fn as_str(&self) -> &str

Get the correlation ID as a string slice.

Trait Implementations

impl Clone for CorrelationId

fn clone(&self) -> CorrelationId

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for CorrelationId

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

Formats the value using the given formatter.

impl Default for CorrelationId

fn default() -> Self

Returns the “default value” for a type.

impl Display for CorrelationId

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

Formats the value using the given formatter.

impl From<&str> for CorrelationId

fn from(id: &str) -> Self

Converts to this type from the input type.

impl From<String> for CorrelationId

fn from(id: String) -> Self

Converts to this type from the input type.

impl Hash for CorrelationId

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 PartialEq for CorrelationId

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