REslava.Result.OpenTelemetry

OpenTelemetry integration for REslava.Result. Seeds ResultContext from the active span and writes error tags as span attributes.

Installation

dotnet add package REslava.Result.OpenTelemetry

Requires REslava.Result ≥ 1.42.0.

What it does

Method Description
.WithOpenTelemetry() Seeds ResultContext.CorrelationId from Activity.Current.TraceId and OperationName from Activity.Current.DisplayName. No-op when no active span.
.WriteErrorTagsToSpan() On failure, writes each error.Tags entry as a span attribute via Activity.Current.SetTag(). No-op when no active span or result is success.

Both methods return the original result unchanged — safe to inline in a pipeline.

Quick Start

using REslava.Result.OpenTelemetry;

var result = await FindUser(userId)
    .WithOpenTelemetry()          // seed CorrelationId + OperationName from active span
    .BindAsync(EnrichUser)
    .EnsureAsync(IsActive, new ForbiddenError())
    .WriteErrorTagsToSpan();      // write error tags to span on failure

Context propagation

.WithOpenTelemetry() integrates with ResultContext — the context then propagates automatically through Bind, Map, Ensure, and other pipeline operators. Error enrichment happens at the end of the pipeline, not at each step.

// What gets set on ResultContext:
// CorrelationId = Activity.Current.TraceId.ToString()
// OperationName = Activity.Current.DisplayName

Zero-cost when inactive

All methods check Activity.Current == null and return immediately — no allocations, no reflection, no overhead outside of an active OpenTelemetry span.
