Std.App.Config.truth

fn

This is a callable function.

What it does

A setting as a truth.

The spellings accepted are the ones a configuration file is actually

written with. A value outside them is refused rather than read as false,

because a setting spelled `yes` that silently means no is worse than one

that stops the program.

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.
