Std.Channel.receive

fn

This is a callable function.

What it does

Take the next value, waiting while the channel is empty.

Nothing means the channel is closed and empty, which is what ends a

receiver's loop. A closed channel still hands out what it already holds:

closing says nothing more will arrive, not that what arrived is discarded.

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.
