Order two wrapped FeeFracs by feerate&period;

== Synopsis

Declared in `&lt;util&sol;feefrac&period;h&gt;`

[source,cpp,subs="verbatim,replacements,macros,-callouts"]
----
std::strong&lowbar;ordering
operator&lt;&equals;&gt;(
    xref:ByRatio.adoc[ByRatio] const& a,
    xref:ByRatio.adoc[ByRatio] const& b) noexcept;
----

== Description

Note that we can use std&colon;&colon;strong&lowbar;ordering here, because even though FeeFrac&lcub;1,2&rcub; and FeeFrac&lcub;2,4&rcub; are distinct as FeeFracs, they are indistinguishable from ByRatio&apos;s perspective (operator&equals;&equals; also treats them as equal)&period;

== Return Value

The ordering of the feerates of a and b&period;

== Parameters

[cols="1,4"]

| Name| Description
| *a*
