Std.App.Otlp.send

fn

This is a callable function.

What it does

Send finished spans to the collector.

Spans that have not finished are left out rather than sent with an ending

they do not have: a span whose end is guessed is worse than a span that is

missing, because it will be read as a measurement.

Answers how many were sent, so a caller can tell an export that carried

nothing from one that carried everything.

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.
• Result makes success and recoverable failure part of the function's type.
