WithSpan | Workflows | Tilebox Go SDK

func WithSpan(
    ctx context.Context,
    name string,
    f func(ctx context.Context) error,
) error

Wrap a function with a tracing span using the current runner’s tracer.

Use WithSpan inside a task Execute method. If the context is not a task execution context, the function runs without creating a span.

Parameters

ctx context.Context required

The task execution context.

name string required

The name of the span.

f func(context.Context) error required

The function to wrap.

Returns

The error returned by f, if any.

Usage example

import (
    "context"
    "fmt"

    "github.com/tilebox/tilebox-go/workflows/v1"
)

type ProcessScene struct{}

func (t *ProcessScene) Execute(ctx context.Context) error {
    err := workflows.WithSpan(
        ctx,
        "write-output",
        func(ctx context.Context) error {
            // Write output here.
            return nil
        },
    )
    if err != nil {
        return fmt.Errorf("failed to write output: %w", err)
    }

    return nil
}
