Std.App.Otlp.document

fn

This is a callable function.

What it does

The document a collector is sent.

Built and answered rather than only sent, because the first thing anyone

debugging a trace pipeline wants is to see exactly what was going to be

sent — and because a service that writes its spans to a file instead of a

collector needs the same document.

Read the signature

• The text after the name is the type checked by Pudu.
• Read arrows from left to right: inputs come first, and the final type is returned.
• & borrows a value for this call instead of moving or copying it.
• Names inside [ ] are type arguments, such as the item type held by a collection.
