Struct FixMessage

pub struct FixMessage { /* private fields */ }

This is the interface you interact with.

The internal message is represented as follows:

FixMessage    := FixComponent
FixComponent  := FixEntity*

FixEntity     := Field | Group

Field         := (tag: i32, value: String)
Group         := FixComponent*

Implementations

impl FixMessage

pub fn from_tag_value(input_message: &str) -> Option<FixMessage>

Creates a FixMessage from an input string encoded in FIX Tag=Value (classic FIX).

Examples

let input = "Recv | 8=FIX.4.4 | 555=2 | 600=CGY | 604=2 | 605=F7 | 605=CGYU0 | 600=CGY | 10=209";
println!("{}", fixparser::FixMessage::from_tag_value(&input).unwrap().to_json());

fn main() -> io::Result<()> {
    println!("Give me a tag-value FIX message, and I will give you a JSON.");
    println!("Do you need help? You can try this one: 8=FIX.4.2 | 10=209");

    let stdin = io::stdin();
    let handle = stdin.lock();

    for line in handle.lines() {
        if let Some(fix_message) = fixparser::FixMessage::from_tag_value(&line?) {
            println!("{}", fix_message.to_json());
        } else {
            println!("Are your sure you gave me a valid FIX message?");
        }
    }

    Ok(())
}

pub fn to_json(&self) -> Value

Get a representation of the message in json string format.

Examples

// this input has the non-printable character 0x01 as the separator of the fields
let input = "8=FIX.4.4
555=2
600=CGY
604=2
605=F7
605=CGYU0
600=CGY
10=209";
println!("{}", fixparser::FixMessage::from_tag_value(&input).unwrap().to_json());

{"8":"FIX.4.4","555":[{"600":"CGY","604":[{"605":"F7"},{"605":"CGYU0"}]},{"600":"CGY"}],"10":"209"}
