details

members

• evtstream\set(event, force)  – push an event value into the stream.
  Marks this stream as dirty for the remainder of the current tick. If event is nil, does nothing.

  parameters:

  • event
  • force
• evtstream.value  – the wrapped Lua value.
  • value (any)

static functions

• EvtStream\new(type)  – construct a new EvtStream.

  parameters:

  • type (type.Type): the type

result interface

• evtstream\dirty()  – return whether this Result was changed in the current tick.

  returns:

  1. (bool)
• evtstream\unwrap([type[, msg]])  – get the sequence of current events (if any).
  Returns value if dirty, or nil otherwise. Asserts @type == type if type is given.

  parameters:

  • type (type.Type): the type to check for (optional)
  • msg (string): message to throw if type don't match (optional)

  returns:

  1. (optional any): value
• evtstream\fork()  – create a mutable copy of this stream.

  returns:

  1. (EvtStream)
• evtstream\__call(...)  – alias for unwrap.

  parameters:

  • ...
• evtstream.type  – the type of this Result's value.
  • type (type.Type)
