Std.Process.closeInput

1 declaration

fn

closeInput: &Std.Process.Started -> Result[(), Str]

This is a callable function.

What it does

Tell a program there is no more input.

Not an optimisation: a program reading until its input ends waits forever

if nothing closes it, so this is the difference between a pipeline that

finishes and one that hangs.

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.
