This library contains all output data types of crypto-msg-parser

.
The crypto_message::compact
module contains compact messages corresponding to message types in lib.rs
.
Differences:
-
Message types in
lib.rs
are output data types ofcrypto-msg-parser
, and they are designed for JSON and CSV. -
Message types in
crypto_message::proto
are protobuf messages, which are designed for disk storage. -
message types in
crypto_message::compact
are suitable for RPC.Messages types in
lib.rs
has string fields such asexchange
,symbol
, which causes a lot of memory allocation and copying, so these types are NOT suitable for high-performance processing.Message types in
crypto_message::proto
are compact, (1) metadata fields such asexchange
,symbol
andpair
are removed to save disk space, because these fields exist in filenames already, and (2) all float numbers are 32-bit to save more disk space.Message types in
crypto_message::compact
are equivalent to message types inlib.rs
, withexchange
changed toenum
,symbol
andpair
changed tou64
hash values.
