final class Pending
Restricted visibility: declared "@visibility root". Code outside that scope must not name this declaration.

One path being walked back from a call: what it passed through, and what it still needs.

The steps are held nearest-first, in the order the walk finds them, and turned around only when the path is run. What is still needed is the set of names no step on the path has defined yet; when it is empty, nothing earlier in the program can change the argument and the walk along this path is done.

Properties§

Methods§

public function __construct(
    public list<SliceStep> $steps,
    public array<string, true> $needs,
    public bool $truncated = false,
    public bool $exhausted = false,
)
source§

Parameters

$stepslist<SliceStep>The steps found so far, nearest to the call first
$needsarray<string, true>The names nothing on the path has defined yet
$truncatedboolWhether a bound cut the path short of every way it could have gone
$exhaustedboolWhether the budget ran out before the path was walked to its start
public static function needing(array<string, true> $needs): self
source§

A path that has gone nowhere yet, needing the given names.

Parameters

$needsarray<string, true>

Returns

self

public function through(SliceStep $step, array<string, true> $needs): self
source§

The path, one step further back.

Parameters

$stepSliceStep
$needsarray<string, true>What the path needs once the step is taken

Returns

self

Calls 2
public function then(self $further): self
source§

The path, followed further back by another path that started where this one stands.

Parameters

$furtherself

self

public function forward(): list<SliceStep>
source§

The steps in the order they run.

Returns

list<SliceStep>

public function signature(): string
source§

What tells this path apart from another that reached the same place.

Returns

string
Test cases 1
Calls 5
public static function gather(non-empty-list<self> $paths): self
source§

Several paths gathered into one, when there are more than it pays to keep apart.

The paths are kept as alternatives of a single step rather than joined value by value, so running it still runs each of them; what is given up is only keeping them apart from the paths that come before them.

Parameters

$pathsnon-empty-list<self>

Returns

self
