Std.Concurrent.parallel
fn
parallel: &Array[fn() -> ()] -> Result[(), Std.Concurrent.ConcurrentError]This is a callable function.
What it does
Run every action at once and wait for all of them.
Every thread is started before any is joined. Starting and joining one at a
time would run them in sequence while looking like it did not, which is the
mistake this exists to make impossible to write by accident.
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.
