Struct FixMessage 

pub struct FixMessage { /* private fields */ }

An ordered collection of FIX fields.

Implementations

impl FixMessage

pub fn new() -> Self

A new, empty message.

pub fn of_type(msg_type: MsgType) -> Self

Build a message of a given type (tag 35). The MsgType field is the first body field; header framing fields (8/9) are added at encode time.

pub fn get(&self, tag: u32) -> Option<&str>

First value for tag, if present.

pub fn get_u64(&self, tag: u32) -> Option<u64>

Convenience: parse a field value as a u64.

pub fn set(&mut self, tag: u32, value: impl Into<String>) -> &mut Self

Set tag to value, replacing the first existing occurrence or appending if absent. Returns &mut self for chaining.

pub fn fields(&self) -> &[FixField]

All fields in insertion order (header framing fields excluded — they are only materialised by to_wire).

pub fn msg_type(&self) -> Option<MsgType>

The message type from tag 35, if present.

pub fn seq_num(&self) -> Option<u64>

The MsgSeqNum (tag 34), if present and numeric.

pub fn to_wire(&self) -> Bytes

Encode the message to wire bytes.

Ordering: 8=BeginString | 9=BodyLength | 35=MsgType | <body…> | 10=CheckSum. BodyLength(9) counts every byte after the SOH that terminates field 9 up to and including the SOH that terminates the last field before CheckSum(10). CheckSum(10) is the sum of all bytes up to and including the SOH before the 10= field, taken mod 256 and rendered as three decimal digits.

pub fn parse(input: &[u8]) -> Result<FixMessage, FixParseError>

Parse a single SOH-delimited FIX frame.

The frame may or may not include the trailing SOH after 10=NNN; both are accepted. When a CheckSum(10) field is present it is verified against the recomputed checksum.

Trait Implementations

impl Clone for FixMessage

fn clone(&self) -> FixMessage

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for FixMessage

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for FixMessage

fn default() -> FixMessage

Returns the “default value” for a type.

impl PartialEq for FixMessage

fn eq(&self, other: &FixMessage) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
