| # Host Side FIDL |
| |
| This document is a short summary of what's available now for host side FIDL, |
| and what may be available in the future. |
| |
| ## What is Available? |
| |
| Encoding and decoding of structs and tables that contain no zircon handles in C++ only. |
| |
| * Use of handles (or consequently FIDL protocol requests and the like) will cause the |
| host side libraries to fail. |
| * In the future this will be verified through a mechanism like NoHandles. |
| |
| ## What is not Available? |
| |
| Any use of protocols. |
| |
| * Trying to use a FIDL file that mentions a protocol will cause the host |
| side runtime to fail to compile. |
| * In the future some verification mechanism will be available here too. |
| |
| ## What is out of scope? |
| |
| Emulation of arbitrary zircon handles (particularly VMO’s). |
| |
| ## What is possibly in scope? |
| |
| Protocols communicating over a socket transport (implies not exchanging handles). |
| |
| ## What is undecided? |
| |
| Emulation of channels on host side (maybe through overnet). |
