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

Source§impl Archive for Mutability
impl Archive for Mutability
Source§type Resolver = MutabilityResolver
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.
Source§fn resolve(&self, resolver: Self::Resolver, out: Place<Self::Archived>)
fn resolve(&self, resolver: Self::Resolver, out: Place<Self::Archived>)
Creates the archived version of this value at the given position and
writes it to the given output. Read more
