pub struct FloatOrd(pub f32);
Expand description
A wrapper for floats that implements Ord
, Eq
, and Hash
traits.
This is a work around for the fact that the IEEE 754-2008 standard,
implemented by Rust’s f32
type,
doesn’t define an ordering for NaN
,
and NaN
is not considered equal to any other NaN
.
Wrapping a float with FloatOrd
breaks conformance with the standard
by sorting NaN
as less than all other numbers and equal to any other NaN
.
Performs copy-assignment from
source
.

This method tests for
self
and
other
values to be equal, and is used
by
==
.
Read more
This method tests for
!=
. The default implementation is almost always
sufficient, and should not be overridden without very good reason.
Read more
This method returns an ordering between
self
and
other
values if one exists.
Read more
This method tests less than (for
self
and
other
) and is used by the
<
operator.
Read more
This method tests less than or equal to (for
self
and
other
) and is used by the
<=
operator.

This method tests greater than (for
self
and
other
) and is used by the
>
operator.

This method tests greater than or equal to (for
self
and
other
) and is used by the
>=
operator.

That is, this conversion is whatever the implementation of
From<T> for U
chooses to do.
