Buffer refactoring in zenoh core #13

Closed Mallets closed 7 months ago

Mallets commented 2 years ago

Discussed in https://github.com/eclipse-zenoh/roadmap/discussions/12

Originally posted by **Mallets** April 11, 2022 ### Summary Current `ZBuf` and `WBuf` implementations are ubiquitously used in zenoh code and bindings. As a result, current implementation needs to accomodate a large set of requirements making it hard to scale and optimise for particular scenarios. A recent [PR](https://github.com/eclipse-zenoh/zenoh/pull/206), introduced common traits for `ZBuf` and `WBuf` implementations. This allows to have targeted buffer implementation that expose a common trait leaving the internal structure tailored to the use case (e.g. serialisation, defragmentation, shared memory, etc.). ### Intended outcome Targeted implementations of `ZBuf` and `WBuf` for different places in the code. As a result, memory management and performance should benefit from it. ### How will it work? Users will still use the same zenoh API that is based on the common traits.
