pub struct SegmentFlags(/* private fields */);
Expand description
Flags for WebAssembly segments.
These flags are defined by implementation at the time of writing: https://github.com/llvm/llvm-project/blob/llvmorg-17.0.6/llvm/include/llvm/BinaryFormat/Wasm.h#L391-L394
Implementations§
§impl SegmentFlags
impl SegmentFlags
pub const STRINGS: SegmentFlags = _
pub const STRINGS: SegmentFlags = _
The segment contains only null-terminated strings, which allows the linker to perform merging.
pub const TLS: SegmentFlags = _
pub const TLS: SegmentFlags = _
The segment contains thread-local data.
§impl SegmentFlags
impl SegmentFlags
pub const fn empty() -> SegmentFlags
pub const fn empty() -> SegmentFlags
Get a flags value with all bits unset.
pub const fn all() -> SegmentFlags
pub const fn all() -> SegmentFlags
Get a flags value with all known bits set.
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<SegmentFlags>
pub const fn from_bits(bits: u32) -> Option<SegmentFlags>
Convert from a bits value.
This method will return None
if any unknown bits are set.
pub const fn from_bits_truncate(bits: u32) -> SegmentFlags
pub const fn from_bits_truncate(bits: u32) -> SegmentFlags
Convert from a bits value, unsetting any unknown bits.
pub const fn from_bits_retain(bits: u32) -> SegmentFlags
pub const fn from_bits_retain(bits: u32) -> SegmentFlags
Convert from a bits value exactly.
pub fn from_name(name: &str) -> Option<SegmentFlags>
pub fn from_name(name: &str) -> Option<SegmentFlags>
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: SegmentFlags) -> bool
pub const fn intersects(&self, other: SegmentFlags) -> bool
Whether any set bits in a source flags value are also set in a target flags value.
pub const fn contains(&self, other: SegmentFlags) -> bool
pub const fn contains(&self, other: SegmentFlags) -> bool
Whether all set bits in a source flags value are also set in a target flags value.
pub fn insert(&mut self, other: SegmentFlags)
pub fn insert(&mut self, other: SegmentFlags)
The bitwise or (|
) of the bits in two flags values.
pub fn remove(&mut self, other: SegmentFlags)
pub fn remove(&mut self, other: SegmentFlags)
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: SegmentFlags)
pub fn toggle(&mut self, other: SegmentFlags)
The bitwise exclusive-or (^
) of the bits in two flags values.
pub fn set(&mut self, other: SegmentFlags, value: bool)
pub fn set(&mut self, other: SegmentFlags, value: bool)
Call insert
when value
is true
or remove
when value
is false
.
pub const fn intersection(self, other: SegmentFlags) -> SegmentFlags
pub const fn intersection(self, other: SegmentFlags) -> SegmentFlags
The bitwise and (&
) of the bits in two flags values.
pub const fn union(self, other: SegmentFlags) -> SegmentFlags
pub const fn union(self, other: SegmentFlags) -> SegmentFlags
The bitwise or (|
) of the bits in two flags values.
pub const fn difference(self, other: SegmentFlags) -> SegmentFlags
pub const fn difference(self, other: SegmentFlags) -> SegmentFlags
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: SegmentFlags) -> SegmentFlags
pub const fn symmetric_difference(self, other: SegmentFlags) -> SegmentFlags
The bitwise exclusive-or (^
) of the bits in two flags values.
pub const fn complement(self) -> SegmentFlags
pub const fn complement(self) -> SegmentFlags
The bitwise negation (!
) of the bits in a flags value, truncating the result.
§impl SegmentFlags
impl SegmentFlags
pub const fn iter(&self) -> Iter<SegmentFlags> ⓘ
pub const fn iter(&self) -> Iter<SegmentFlags> ⓘ
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<SegmentFlags> ⓘ
pub const fn iter_names(&self) -> IterNames<SegmentFlags> ⓘ
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.
