Create a `Rule` with the specified pattern and threshold levels.

== Synopsis

Declared in `<ball_rule.h>`

[source,cpp,subs="verbatim,replacements,macros,-callouts"]
----
Rule(
    std::string_view const& pattern,
    int recordLevel,
    int passLevel,
    int triggerLevel,
    int triggerAllLevel,
    xref:BloombergLP/bslma/Allocator.adoc[bslma::Allocator]* basicAllocator = 0);
----

== Description

Create a `Rule` object whose pattern is the specified `pattern` and whose thresholds levels are the specified `recordLevel`, `passLevel`, `triggerLevel`, and `triggerAllLevel` respectively. Optionally specify a `basicAllocator` used to supply memory. If `basicAllocator` is 0, the currently installed default allocator will be used. The behavior is undefined unless each of the four threshold level values is not in the range [0 .. 255]. Note that a newly created `Rule` object does not have any attributes.
