Member Data Documentation

RequestHeaderPrefix LogCabin::RPC::Protocol::RequestHeaderVersion1::prefix

This is common to all versions of the protocol.

RPC servers can always expect to receive this and RPC clients must always send this.

Definition at line 83 of file Protocol.h.

uint16_t LogCabin::RPC::Protocol::RequestHeaderVersion1::service

This identifies which Service the RPC is destined for.

See Protocol::Common::ServiceId.

Definition at line 89 of file Protocol.h.

uint8_t LogCabin::RPC::Protocol::RequestHeaderVersion1::serviceSpecificErrorVersion

This field tells the service what service-specific errors the client understands.

Clients should remain backwards-compatible, so that newer clients can understand older errors. Services should take care not to send a client a service-specific error that it doesn't understand.

Definition at line 97 of file Protocol.h.

uint16_t LogCabin::RPC::Protocol::RequestHeaderVersion1::opCode

This identifies which RPC is being executed, scoped to the service.

Definition at line 102 of file Protocol.h.
