Std.Log.failure

fn

This is a callable function.

What it does

Write a failure's cause at Error, and answer the failure unchanged.

Answering it back means a caller logs on the way past rather than choosing

between reporting a failure and returning it.

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.
