This improves sc-service API by not requiring the whole &Configuration, using specific configuration options instead. RpcConfiguration was also extracted from Configuration to group all RPC options together.

We don't use Substrate's CLI and would rather not use Configuration either, but some key public functions require it even though they ignored most of the fields anyway.

RpcConfiguration is very helpful not just for consolidation of the fields, but also to finally make RPC optional for our use case, while Substrate still runs RPC server on localhost even if listening address is explicitly set to None, which is annoying (and I suspect there is a reason for it, so didn't want to change the default just yet).

While this is a breaking change, most developers will not notice it if they use higher-level APIs.

Fixes #2897

Would ExecutorConfiguration be a good name for use with new_wasm_executor that combines the following options?:

  • default_heap_pages
  • wasm_method
  • max_runtime_instances
  • runtime_cache_size

This is probably the last thing that I'd like to stop using &Configuration for now.

…ons, introduce `sc_service::config::RpcConfiguration` to replace a bunch of flat fields

while Substrate still runs RPC server on localhost even if listening address is explicitly set to None, which is annoying (and I suspect there is a reason for it, so didn't want to change the default just yet).

I suppose you want to start your service without any rpc server then? Can you open an issue for it please?

I don't remember why we do it but that can changed if desired also with the latest refactoring it should be possible do addr: Some(vec![]) as workaround but I think it will throw an error when no rpc listen addr is found and bail early with the error.

This improves `sc-service` API by not requiring the whole
`&Configuration`, using specific configuration options instead.
`RpcConfiguration` was also extracted from `Configuration` to group all
RPC options together.

either, but some key public functions require it even though they
ignored most of the fields anyway.
