fn pub !=(other: T) -> Bool {
  (self == other).false?
}

fn pub !=(other: T) -> Bool

Returns true if self and the given object are not equal to each other.

fn pub ==(other: ref Signal) -> Bool {
  id == other.id
}

fn pub ==(other: ref Signal) -> Bool

Returns true if self and the given object are equal to each other.

This operator is used to perform structural equality. This means two objects residing in different memory locations may be considered equal, provided their structure is equal. For example, two different arrays may be considered to have structural equality if they contain the exact same values.

fn pub clone -> Signal {
  match self {
    case Hangup -> Signal.Hangup
    case Interrupt -> Signal.Interrupt
    case Quit -> Signal.Quit
    case Abort -> Signal.Abort
    case User1 -> Signal.User1
    case User2 -> Signal.User2
    case Terminate -> Signal.Terminate
    case Child -> Signal.Child
    case Continue -> Signal.Continue
    case Stop -> Signal.Stop
    case Input -> Signal.Input
    case Output -> Signal.Output
    case FileSizeExceeded -> Signal.FileSizeExceeded
    case Resize -> Signal.Resize
  }
}

fn pub clone -> Signal

Creates a clone of self.

fn pub fmt(formatter: mut Formatter) {
  let name = match self {
    case Hangup -> 'Hangup'
    case Interrupt -> 'Interrupt'
    case Quit -> 'Quit'
    case Abort -> 'Abort'
    case User1 -> 'User1'
    case User2 -> 'User2'
    case Terminate -> 'Terminate'
    case Child -> 'Child'
    case Continue -> 'Continue'
    case Stop -> 'Stop'
    case Input -> 'Input'
    case Output -> 'Output'
    case FileSizeExceeded -> 'FileSizeExceeded'
    case Resize -> 'Resize'
  }

  formatter.tuple(name).finish
}

fn pub fmt(formatter: mut Formatter)

Formats self in a human-readable format for debugging purposes.

fn pub hash[H: mut + Hasher](hasher: mut H) {
  hasher.write(id)
}

fn pub hash[H: mut + Hasher](hasher: mut H: mut)

Writes the hash for self into the given Hasher.

fn pub wait {
  inko_signal_wait(_INKO.state, _INKO.process, id)
}

fn pub wait

Waits for the signal to arrive before returning.

If the signal is sent before this call finishes setting up the signal handler, this method doesn't return until the next time the signal is received.

It's possible for multiple processes to call Signal.wait using the same signal. In this case receiving the signal results in all those Signal.wait calls returning. However, the order in which those calls return is unspecified and shouldn't be relied upon.

No guarantees are made as to the time between receiving the signal and this method returning: it may be more or less instantly, or it could take some time.

When returning from this method and no other processes are waiting for the same signal to be received, the default signal handler is restored.

Examples

import std.signal (Signal)

Signal.User1.wait
