Std.Test.all

fn

This is a callable function.

What it does

A check that holds when every value satisfies the test.

The first value that does not is what the failure names, because the reader

wants the one that broke rather than the count of those that did not.

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.
