pub trait MutabilityExt {

    fn is_permissive_as(self, other: Self) -> bool;
}Required Methods§
Sourcefn is_permissive_as(self, other: Self) -> bool
 
fn is_permissive_as(self, other: Self) -> bool
Returns true if self is equally or more permissive than other,
i.e. where Not is more permissive than Mut.
This corresponds to the relation $\omega_1 \lesssim \omega_2$ in the Flowistry paper.
Dyn Compatibility§
This trait is not dyn compatible.
In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
