Expand description
Flags for WebAssembly symbols.
These flags correspond to those described in
https://github.com/WebAssembly/tool-conventions/blob/main/Linking.md
with the WASM_SYM_*
prefix.
Implementations§
source§impl SymbolFlags
impl SymbolFlags
sourcepub const BINDING_WEAK: Self = _
pub const BINDING_WEAK: Self = _
This is a weak symbol.
sourcepub const BINDING_LOCAL: Self = _
pub const BINDING_LOCAL: Self = _
This is a local symbol (this is exclusive with [BINDING_WEAK]).
sourcepub const VISIBILITY_HIDDEN: Self = _
pub const VISIBILITY_HIDDEN: Self = _
This is a hidden symbol.
sourcepub const EXPORTED: Self = _
pub const EXPORTED: Self = _
This symbol is intended to be exported from the wasm module to the host environment.
sourcepub const EXPLICIT_NAME: Self = _
pub const EXPLICIT_NAME: Self = _
This symbol uses an explicit symbol name, rather than reusing the name from a wasm import.

impl SymbolFlags
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 SymbolFlags
impl SymbolFlags
sourcepub const fn iter(&self) -> Iter<SymbolFlags>
pub const fn iter(&self) -> Iter<SymbolFlags>
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<SymbolFlags>
pub const fn iter_names(&self) -> IterNames<SymbolFlags>
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.
