Std.Process.readErrors

fn

This is a callable function.

What it does

The same for what a program wrote to its error stream.

Kept apart from its output rather than merged, because a caller reading

output as data — a pipeline, a parser — must not find a warning in the

middle of 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.
• Option holds Some(value) or None when no value is available.
• Result makes success and recoverable failure part of the function's type.
