This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".

Implementors

impl AeronReservedValueSupplierCallback for AeronReservedValueSupplierLogger

impl AeronReservedValueSupplierCallback for NoHandler

impl<F: FnMut(&mut [u8]) -> i64> AeronReservedValueSupplierCallback for F

Any closure with the matching signature is a callback: methods that retain it heap-allocate it into a Handler owned by the registering resource.

impl<T: AeronReservedValueSupplierCallback> AeronReservedValueSupplierCallback for Handler<T>

Pass an existing Handler clone anywhere a callback value is expected, e.g. to share one callback instance across several registrations.
