pub struct TraceId(_);
Available on crate feature trace only.
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

Helper to create trace ids for testing

Invalid trace id

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

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

Converts a string in base 16 to a trace id.

Examples
use opentelemetry_api::trace::TraceId;

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

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