fixparser

Parse FIX messages without a FIX dictionary.

[dependencies] fixparser = "0.1.0"

It currently supports the following input/output formats:

Input:

FIX Tag=Value (classic FIX)

Output:

Json (serde_json::value::Value)

Examples

```rust let input = "Recv | 8=FIX.4.4 | 555=2 | 600=CGY | 604=2 | 605=F7 | 605=CGYU0 | 600=CGY | 604=2 | 605=F7 | 605=CGYM0 | 10=209";

if let Some(fixmessage) = fixparser::FixMessage::fromtagvalue(&input) { println!("{}", fixmessage.to_json()); } ```

rust // this input has the non-printable character 0x01 as the separator of the fields let input = "8=FIX.4.4555=2600=CGY604=2605=F7605=CGYU0600=CGY604=2605=F7605=CGYM010=20"; if let Some(fix_message) = fixparser::FixMessage::from_tag_value(&input) { println!("{}", fix_message.to_json()); }

See tests/ folder for more examples

Goodies

It supports groups and you don't need a FIX dictionary
You don't need to specify the separator of the input string as long as they are consistent. eg: 0x01, |, etc...
You don't need to "trim" the input string as the lib detects the beginning and end of the message

Limitations

There are a few scenarios the library can't parse as it can't guess the format of the message without a dictionary:

8=FIX.4.4 | 1000=2 | 1001=1 | 1002=2 | 1001=10 | 1002=20 | 1003=30 | 10=209 ^ ^ group 1000 does 1003 belong to the second repetition of group 1000?
