workflows.WithSpan

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

Copy

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.
