Struct azul_webrender_api::ImageDescriptorFlags [−][src]
pub struct ImageDescriptorFlags { /* fields omitted */ }
Expand description
Various flags that are part of an image descriptor.
Implementations
Whether this image is opaque, or has an alpha channel. Avoiding blending for opaque surfaces is an important optimization.
Whether to allow the driver to automatically generate mipmaps. If images are already downscaled appropriately, mipmap generation can be wasted work, and cause performance problems on some cards/drivers.
See https://github.com/servo/webrender/pull/2555/
Returns an empty set of flags
Returns the set containing all flags.
Convert from underlying bit representation, unless that representation contains bits that do not correspond to a flag.
Convert from underlying bit representation, dropping any bits that do not correspond to flags.
Convert from underlying bit representation, preserving all bits (even those not corresponding to a defined flag).
Returns true
if there are flags common to both self
and other
.
Returns true
all of the flags in other
are contained within self
.
Inserts the specified flags in-place.
Removes the specified flags in-place.
Toggles the specified flags in-place.
Inserts or removes the specified flags depending on the passed value.

type Output = ImageDescriptorFlags
The resulting type after applying the ^
operator.
