Std.Process.runLaunch

1 declaration

fn

runLaunch: &Std.Process.Launch -> Str -> Result[Std.Process.Finished, Str]

This is a callable function.

What it does

Run a launch to completion with text on its input.

The error stream is read on its own worker while output is read here, so a

program writing a lot to both cannot stall on a full pipe nobody is reading.

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.
