Struct opentelemetry::trace::TraceId

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

A 16-byte value which identifies a given trace.

The id is valid if it contains at least one non-zero byte.

Implementations

impl TraceId

pub const INVALID: TraceId = _

Invalid trace id

pub const fn from_bytes(bytes: [u8; 16]) -> Self

Create a trace id from its representation as a byte array.

pub const fn to_bytes(self) -> [u8; 16]

Return the representation of this trace id as a byte array.

pub fn from_hex(hex: &str) -> Result<Self, ParseIntError>

Converts a string in base 16 to a trace id.

Examples

use opentelemetry::trace::TraceId;

assert!(TraceId::from_hex("42").is_ok());
assert!(TraceId::from_hex("58406520a006649127e371903a2de979").is_ok());

assert!(TraceId::from_hex("not_hex").is_err());

Trait Implementations

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<'de> Deserialize<'de> for TraceId

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

Deserialize this value from the given Serde deserializer.

impl Display for TraceId

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

Formats the value using the given formatter.

impl From<[u8; 16]> for TraceId

fn from(bytes: [u8; 16]) -> Self

Converts to this type from the input type.

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 LowerHex for TraceId

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

Formats the value using the given formatter.

impl PartialEq for TraceId

fn eq(&self, other: &TraceId) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serialize for TraceId

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

Serialize this value into the given Serde serializer.
