Std.Channel.drain

1 declaration

fn

drain: &Std.Channel.Channel[T] -> Result[Array[T], Std.Channel.ChannelError]

This is a callable function.

What it does

Every value still to come, in the order it was sent.

Named so its cost is visible: this holds every value at once, and `fold` is

the one that does 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.
  • Result makes success and recoverable failure part of the function's type.
