Enum Mutability

#[repr(u8)]
pub enum Mutability {
    Const = 0,
    Var = 1,
}

Indicator of whether a global is mutable or not

Variants

Const = 0

The global is constant and its value does not change

Var = 1

The value of the global can change over time

Implementations

impl Mutability

pub fn is_mutable(self) -> bool

Returns a boolean indicating if the enum is set to mutable.

Trait Implementations

impl Archive for Mutability

type Archived = Mutability

The archived representation of this type.

type Resolver = MutabilityResolver

The resolver for this type. It must contain all the additional information from serializing needed to make the archived type from the normal type.

unsafe fn resolve( &self, pos: usize, resolver: <Self as Archive>::Resolver, out: *mut <Self as Archive>::Archived, )

Creates the archived version of this value at the given position and writes it to the given output.

impl<__C: ?Sized> CheckBytes<__C> for Mutability

type Error = EnumCheckError<u8>

The error that may result from checking the type.

unsafe fn check_bytes<'__bytecheck>( value: *const Self, context: &mut __C, ) -> Result<&'__bytecheck Self, EnumCheckError<u8>>

Checks whether the given pointer points to a valid value within the given context.

impl Clone for Mutability

fn clone(&self) -> Mutability

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Mutability

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<__D: Fallible + ?Sized> Deserialize<Mutability, __D> for Archived<Mutability>

fn deserialize(&self, deserializer: &mut __D) -> Result<Mutability, __D::Error>

Deserializes using the given deserializer

impl From<Mutability> for bool

fn from(value: Mutability) -> Self

Converts to this type from the input type.

impl From<bool> for Mutability

fn from(value: bool) -> Self

Converts to this type from the input type.

impl Hash for Mutability

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for Mutability

fn eq(&self, other: &Mutability) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl<__S: Fallible + ?Sized> Serialize<__S> for Mutability

fn serialize( &self, serializer: &mut __S, ) -> Result<<Self as Archive>::Resolver, __S::Error>

Writes the dependencies for the object and returns a resolver that can create the archived type.

impl Copy for Mutability

impl Eq for Mutability

impl StructuralPartialEq for Mutability
