exception Rpc_dir_creation_failure of Tezos_base.TzPervasives.tztrace
Exception used by the proxy mode when creation of the input environment (of the RPC handler) fails. This exception is used to temporarily escape from the monad, because at the point of throwing, the code is NOT in tzresult Lwt.t
. As it's dealing with resto APIs it's in an Lwt.t
-only monad. This exception is injected back in the tzresult Lwt.t
monad at the point where it is caught (with Lwt.catch
).

is running. Thesleep
field is implemented byLwt_unix.sleep
. We don't want to depend on it directly (for compiling to Javascript), hence this field. ThePtime.span option
field is the value of argument--sym-block-caching-time
. The(Context_hash.t -> Proxy_delegate.t tzresult Lwt.t) option
value is constructed from argument--data-dir
: if the argument is present, this value represents how data is looked up in the data-dir of a running node.

or tezos-proxy-server
