Implementations§
source§impl Workarounds
impl Workarounds
sourcepub const SEPARATE_ENTRY_POINTS: Self = _
pub const SEPARATE_ENTRY_POINTS: Self = _
Only generate SPIR-V for one entry point at a time.
sourcepub const EMPTY_RESOLVE_ATTACHMENT_LISTS: Self = _
pub const EMPTY_RESOLVE_ATTACHMENT_LISTS: Self = _
Qualcomm OOMs when there are zero color attachments but a non-null pointer to a subpass resolve attachment array. This nulls out that pointer in that case.
sourcepub const FORCE_FILL_BUFFER_WITH_SIZE_GREATER_4096_ALIGNED_OFFSET_16: Self = _
pub const FORCE_FILL_BUFFER_WITH_SIZE_GREATER_4096_ALIGNED_OFFSET_16: Self = _
If the following code returns false, then nvidia will end up filling the wrong range.
fn nvidia_succeeds() -> bool {
# let (copy_length, start_offset) = (0, 0);
if copy_length >= 4096 {
if start_offset % 16 != 0 {
if copy_length == 4096 {
return true;
}
if copy_length % 16 == 0 {
return false;
}
}
}
true
}
As such, we need to make sure all calls to vkCmdFillBuffer are aligned to 16 bytes if they cover a range of 4096 bytes or more.
source§impl Workarounds
impl Workarounds
sourcepub 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.
sourcepub const fn from_bits(bits: u32) -> Option<Self>
pub const fn from_bits(bits: u32) -> Option<Self>
Convert from a bits value.
This method will return None
if any unknown bits are set.
sourcepub const fn from_bits_truncate(bits: u32) -> Self
pub const fn from_bits_truncate(bits: u32) -> Self
Convert from a bits value, unsetting any unknown bits.
sourcepub const fn from_bits_retain(bits: u32) -> Self
pub const fn from_bits_retain(bits: u32) -> Self
Convert from a bits value exactly.
sourcepub fn from_name(name: &str) -> Option<Self>
pub fn from_name(name: &str) -> Option<Self>
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.
sourcepub const fn intersects(&self, other: Self) -> bool
pub const fn intersects(&self, other: Self) -> bool
Whether any set bits in a source flags value are also set in a target flags value.
sourcepub const fn contains(&self, other: Self) -> bool
pub const fn contains(&self, other: Self) -> bool
Whether all set bits in a source flags value are also set in a target flags value.
sourcepub fn remove(&mut self, other: Self)
pub fn remove(&mut self, other: Self)
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.
sourcepub fn toggle(&mut self, other: Self)
pub fn toggle(&mut self, other: Self)
The bitwise exclusive-or (^
) of the bits in two flags values.
sourcepub fn set(&mut self, other: Self, value: bool)
pub fn set(&mut self, other: Self, value: bool)
Call insert
when value
is true
or remove
when value
is false
.
sourcepub const fn intersection(self, other: Self) -> Self
pub const fn intersection(self, other: Self) -> Self
The bitwise and (&
) of the bits in two flags values.
sourcepub const fn union(self, other: Self) -> Self
pub const fn union(self, other: Self) -> Self
The bitwise or (|
) of the bits in two flags values.
sourcepub const fn difference(self, other: Self) -> Self
pub const fn difference(self, other: Self) -> Self
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.
sourcepub const fn symmetric_difference(self, other: Self) -> Self
pub const fn symmetric_difference(self, other: Self) -> Self
The bitwise exclusive-or (^
) of the bits in two flags values.
sourcepub const fn complement(self) -> Self
pub const fn complement(self) -> Self
The bitwise negation (!
) of the bits in a flags value, truncating the result.
source§impl Workarounds
impl Workarounds
sourcepub const fn iter(&self) -> Iter<Workarounds>
pub const fn iter(&self) -> Iter<Workarounds>
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.
sourcepub const fn iter_names(&self) -> IterNames<Workarounds>
pub const fn iter_names(&self) -> IterNames<Workarounds>
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.
