Expand description
State of a single viewport.
Coordinates in pixels of the top-left hand corner of the viewport.
Dimensions in pixels of the viewport.
Minimum and maximum values of the depth.
The values 0.0
to 1.0
of each vertex’s Z coordinate will be mapped to this
depth_range
before being compared to the existing depth value.
This is equivalents to glDepthRange
in OpenGL, except that OpenGL uses the Z coordinate
range from -1.0
to 1.0
instead.
Performs copy-assignment from
source
.

Converts to this type from the input type.
This method tests for
self
and
other
values to be equal, and is used
by
==
.

This method tests for
!=
. The default implementation is almost always
sufficient, and should not be overridden without very good reason.

Returns the argument unchanged.
Calls U::from(self)
.
That is, this conversion is whatever the implementation of
From<T> for U
chooses to do.
The resulting type after obtaining ownership.
