# workflows.WithTaskSpan

import { Fragment } from "astro/jsx-runtime";

import ApiReference from "@docs/components/ApiReference.astro";

import ParamField from "@docs/components/ParamField.astro";

```go
workflows.WithTaskSpan(
    ctx context.Context,
    name string,
    f func(ctx context.Context) error,
) error
```

Wrap a function with a [tracing span](/docs/workflows/run-and-inspect/tracing) using the current runner's tracer.

`WithTaskSpan` is an alias for [`WithSpan`](/docs/api-reference/go/workflows/WithSpan). Use it inside a task `Execute` method. If the context is not a task execution context, the function runs without creating a span.

## Parameters

**ctx**

type: context.Context

required: true

The task execution context.
**name**

type: string

required: true

The name of the span.
**f**

type: func(context.Context) error

required: true

The function to wrap.

## Returns

The error returned by `f`, if any.

<h2 id="request-example">Usage example</h2>

```go
type Task struct{}

func (t *Task) Execute(ctx context.Context) error {
	err := workflows.WithTaskSpan(
		ctx,
		"Database insert",
		func(ctx context.Context) error {
			// Do something
			return nil
		},
	)
  if err != nil {
    return fmt.Errorf("failed to insert into database: %w", err)
  }

	return nil
}
```
