Required Methods§

Source

fn allows_sharing_update( socketmap: &SocketMap<AddrVec<I, D, A>, Bound<Self>>, addr: &Addr, old_sharing: &SharingState, new_sharing: &SharingState, ) -> Result<(), UpdateSharingError>

Returns whether the entry addr in socketmap allows the sharing state to transition from old_sharing to new_sharing.

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.
