Std.Result.all

fn

This is a callable function.

What it does

Every success, or the first failure.

This is how a caller turns many fallible steps into one answer without

deciding, at each step, whether to keep going.

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.
