Struct TraceId

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

A Honeycomb Trace ID.

Uniquely identifies a single distributed trace.

Does no parsing on string input values. Can be generated new from a UUID V4.

Display and FromStr are guaranteed to round-trip.

Implementations

impl TraceId

pub fn meta_field_name() -> &'static str

Metadata field name associated with this TraceId values.

pub fn new() -> Self

Generate a new TraceId from a UUID V4.

pub fn generate() -> Self

👎Deprecated since 0.2.0: Use TraceId::new() instead.

Generate a new TraceId from a UUID V4.

Prefer TraceId::new().

Trait Implementations

impl AsRef<[u8]> for TraceId

fn as_ref(&self) -> &[u8]

Converts this type into a shared reference of the (usually inferred) input type.

impl Clone for TraceId

fn clone(&self) -> TraceId

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for TraceId

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

Formats the value using the given formatter.

impl Default for TraceId

fn default() -> Self

Returns the “default value” for a type.

impl Display for TraceId

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

Formats the value using the given formatter.

impl From<&str> for TraceId

fn from(s: &str) -> Self

Converts to this type from the input type.

impl From<Cow<'_, &str>> for TraceId

fn from(s: Cow<'_, &str>) -> Self

Converts to this type from the input type.

impl From<String> for TraceId

fn from(s: String) -> Self

Converts to this type from the input type.

impl From<TraceId> for String

fn from(trace_id: TraceId) -> String

Converts to this type from the input type.

impl From<Uuid> for TraceId

fn from(uuid: Uuid) -> Self

Converts to this type from the input type.

impl From<u128> for TraceId

fn from(u: u128) -> Self

Converts to this type from the input type.

impl FromStr for TraceId

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

Is actually infalliable.

type Err = Infallible

The associated error which can be returned from parsing.

impl Hash for TraceId

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 TraceId

fn eq(&self, other: &TraceId) -> 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 TryFrom<TraceId> for Uuid

type Error = Error

The type returned in the event of a conversion error.

fn try_from(trace_id: TraceId) -> Result<Uuid, Self::Error>

Performs the conversion.

impl TryFrom<TraceId> for u128

type Error = Error

The type returned in the event of a conversion error.

fn try_from(trace_id: TraceId) -> Result<u128, Self::Error>

Performs the conversion.
