opentelemetry::trace

Struct TraceId

source
pub struct TraceId(/* private fields */);
Expand description

A 16-byte value which identifies a given trace.

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

Implementations§

source§

impl TraceId

source

pub const INVALID: TraceId = _

Invalid trace id

source

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

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

source

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

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

source

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());
