Std.Text.countOf

fn

This is a callable function.

What it does

The count this text spells, or nothing.

A count is never below nothing, so a sign is not admitted rather than

admitted and then rejected somewhere later. This is the reading a length, a

port, a quantity, or an index wants: -1 is not a short length, it is not a

length, and the difference is worth having in the type of the answer rather

than in a check every caller remembers.

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.
• Names inside [ ] are type arguments, such as the item type held by a collection.
• Option holds Some(value) or None when no value is available.
