Std.Channel.pending

fn

This is a callable function.

What it does

How many values are waiting.

A number that was true when it was read and may not be by the time it is

used, because another thread may send or receive in between. Right for a

report and wrong as a reason to skip a wait.

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.
