Struct hotfix_encoding::decoder::Decoder

pub struct Decoder { /* private fields */ }

FIX message decoder.

One should create a Decoder per stream of FIX messages.

Implementations

impl Decoder

pub fn new(dict: Dictionary) -> Self

Creates a new Decoder for the tag-value format. dict is used to parse messages.

pub fn streaming<B>(self, buffer: B) -> DecoderStreaming<B>where B: Buffer,

Adds a [Buffer] to self, turning it into a [StreamingDecoder].

pub fn decode<T>(&mut self, bytes: T) -> Result<Message<'_, T>, DecodeError>where T: AsRef<[u8]>,

Decodes data and returns an immutable reference to the obtained message.

Examples

use hotfix_dictionary::{Dictionary};
use hotfix_encoding::fix44;
use hotfix_encoding::config::{Config, GetConfig};
use hotfix_encoding::decoder::Decoder;
use hotfix_encoding::field_access::FieldMap;

let dict = Dictionary::fix44();
let mut decoder = Decoder::new(dict);
decoder.config_mut().separator = b'|';
let data = b"8=FIX.4.4|9=42|35=0|49=A|56=B|34=12|52=20100304-07:59:30|10=185|";
let message = decoder.decode(data).unwrap();
assert_eq!(message.get(fix44::SENDER_COMP_ID), Ok("A"));
