[Obsolete("Use Google.Cloud.Diagnostics.Common.ITraceContext instead.")]public sealed class TraceContextForLogEntry
Represents a trace context (Trace ID and Span ID)
for a log entry.
These values can be attached to a log entry to establish the
relation of it and a trace.
For this to be matched to a span being stored in Google Cloud Trace,
its format should be the same that the Trace API v2 uses: a 16-character hexadecimal
encoding of an 8-byte array, such as 000000000000004a. A check is not performed
to ensure this format is used, so as to allow for this value to refer to spans other
than those stored in Google Cloud Trace.
TraceId
public string TraceId { get; }
The trace ID to associate the log entry with.
Must not be null.
