only.Expand description
Ray flags, for a RayDesc
’s flags
field.
Note that these exactly correspond to the SPIR-V “Ray Flags” mask, and
the SPIR-V backend passes them directly through to the
OpRayQueryInitializeKHR
instruction. (We have to choose something, so
we might as well make one back end’s life easier.)

§impl RayFlag
impl RayFlag
pub const fn bits(&self) -> u32
pub const fn bits(&self) -> u32
Get the underlying bits value.
The returned value is exactly the bits set in this flags value.
pub const fn from_bits(bits: u32) -> Option<RayFlag>
pub const fn from_bits(bits: u32) -> Option<RayFlag>
Convert from a bits value.
This method will return None
if any unknown bits are set.
pub const fn from_bits_truncate(bits: u32) -> RayFlag
pub const fn from_bits_truncate(bits: u32) -> RayFlag
Convert from a bits value, unsetting any unknown bits.
pub const fn from_bits_retain(bits: u32) -> RayFlag
pub const fn from_bits_retain(bits: u32) -> RayFlag
Convert from a bits value exactly.
pub fn from_name(name: &str) -> Option<RayFlag>
pub fn from_name(name: &str) -> Option<RayFlag>
Get a flags value with the bits of a flag with the given name set.
This method will return None
if name
is empty or doesn’t
correspond to any named flag.
pub const fn intersects(&self, other: RayFlag) -> bool
pub const fn intersects(&self, other: RayFlag) -> bool
Whether any set bits in a source flags value are also set in a target flags value.
pub const fn contains(&self, other: RayFlag) -> bool
pub const fn contains(&self, other: RayFlag) -> bool
Whether all set bits in a source flags value are also set in a target flags value.
pub fn remove(&mut self, other: RayFlag)
pub fn remove(&mut self, other: RayFlag)
The intersection of a source flags value with the complement of a target flags value (&!
).
This method is not equivalent to self & !other
when other
has unknown bits set.
remove
won’t truncate other
, but the !
operator will.
pub fn toggle(&mut self, other: RayFlag)
pub fn toggle(&mut self, other: RayFlag)
The bitwise exclusive-or (^
) of the bits in two flags values.
pub fn set(&mut self, other: RayFlag, value: bool)
pub fn set(&mut self, other: RayFlag, value: bool)
Call insert
when value
is true
or remove
when value
is false
.
pub const fn intersection(self, other: RayFlag) -> RayFlag
pub const fn intersection(self, other: RayFlag) -> RayFlag
The bitwise and (&
) of the bits in two flags values.
pub const fn union(self, other: RayFlag) -> RayFlag
pub const fn union(self, other: RayFlag) -> RayFlag
The bitwise or (|
) of the bits in two flags values.
pub const fn difference(self, other: RayFlag) -> RayFlag
pub const fn difference(self, other: RayFlag) -> RayFlag
The intersection of a source flags value with the complement of a target flags value (&!
).
This method is not equivalent to self & !other
when other
has unknown bits set.
difference
won’t truncate other
, but the !
operator will.
pub const fn symmetric_difference(self, other: RayFlag) -> RayFlag
pub const fn symmetric_difference(self, other: RayFlag) -> RayFlag
The bitwise exclusive-or (^
) of the bits in two flags values.
pub const fn complement(self) -> RayFlag
pub const fn complement(self) -> RayFlag
The bitwise negation (!
) of the bits in a flags value, truncating the result.
§impl RayFlag
impl RayFlag
pub const fn iter(&self) -> Iter<RayFlag>
pub const fn iter(&self) -> Iter<RayFlag>
Yield a set of contained flags values.
Each yielded flags value will correspond to a defined named flag. Any unknown bits will be yielded together as a final flags value.
pub const fn iter_names(&self) -> IterNames<RayFlag>
pub const fn iter_names(&self) -> IterNames<RayFlag>
Yield a set of contained named flags values.
This method is like iter
, except only yields bits in contained named flags.
Any unknown bits, or bits not corresponding to a contained flag will not be yielded.
