NAME

    Devel::MAT::Tool::Future - analyse Future logic

DESCRIPTION

    This Devel::MAT tool performs analysis of objects and code logic built
    using the Future module.

    This version supports analysing code based on Future version 0.24.

METHODS

 class_is_future

       $ok = $tool->class_is_future( $pkg )

    Returns true if the given package is a Future class. $pkg may be either
    a Devel::MAT::SV instance referring to a stash, or a plain string.

SV METHODS

    This tool adds the following SV methods.

 is_future (SV)

       $ok = $sv->is_future

    Returns true if the Devel::MAT::SV instance represents a Future
    instance.

 future_state (SV)

       $state = $sv->future_state

    Returns a string describing the state of the given Future instance; one
    of pending, done, failed or cancelled.

 future_result

       @result = $sv->future_result

    Returns a list of SVs containing the result of a successful Future.

 future_failure

       @failure = $sv->future_failure

    Returns a list of SVs containing the failure of a failed Future.

EXTENSIONS TO FIND

 find future

       pmat> find future -f
       HASH(2)=Future at 0x55d43c854660: Future(failed) - SCALAR(PV) at 0x55d43c8546f0 = "It failed"

    Lists SVs that are Future instances, optionally matching only futures
    in a given state.

    Takes the following named options

    --pending, -p

      Lists only Futures in the pending state

    --done, -d

      Lists only Futures in the done state

    --failed, -f

      Lists only Futures in the failed state

    --cancelled, -c
