go - Should you use protobuf as the datatype you use for processing or only for transmission? -


i have matrix struct written in go. matrix struct has bunch of methods. want able efficiently compute matrix operations want able send on wire in order distribute computation.

i have matrix , methods separate protobuf definition. when need send on wire have create new pb.matrix{} existing matrix{} struct , make grpc call. seems waste. so, waste? , should defining matrix struct protobuf definition , use embedding define operations on it? or better keep them separate each other?

in terms of architecture, i'd keep them separate. agree single responsibility principle. in 1 of projects use form:

type foo struct { ... }  func newfoofromproto(f *myproto.foo) *foo { ... }  func (f *foo) toproto() *myproto.foo { ... }

Retrieving ETA (estimated time of arrival) with Google Distance Matrix API and public transit as transport mode -

Image
is possible retrieve eta google's distancematrix api (or alternative api). fyi, eta different duration, when using public transport. following example clarify request. when leave on friday @ 8.15 i'll able catch train @ 8.30 , arrive @ 9.00 am. google says duration 30 minutes. however, when leave on saturday @ 8.15 i'll able catch first train @ 9.00 , arrive @ 9.30 am. google still says duration 30 minutes, means ignore delay. google map supports functionality there api around giving me eta instead of duration. can see, distance-matrix' response no good. clarifying question little. eta estimated time of arrival , it's clear user wants know entire duration of transport (including waiting time public transport).
