Struct fefix::tagvalue::Message

pub struct Message<'a, T> { /* fields omitted */ }

A FIX message returned by Decoder or DecoderBuffered.

Implementations

impl<'a, T> Message<'a, T>

pub fn fields(&'a self) -> Fields<'a, T>

Returns an Iterator over all fields in self, in sequential order starting from the very first field.

Examples

use fefix::tagvalue::{Config, Decoder};
use fefix::prelude::*;

const DATA: &[u8] = b"8=FIX.4.4|9=42|35=0|49=A|56=B|34=12|52=20100304-07:59:30|10=185|";

let mut decoder = Decoder::<Config>::new(Dictionary::fix44());
decoder.config_mut().set_separator(b'|');

let message = decoder.decode(DATA).unwrap();
let first_field = message.fields().next();

assert_eq!(first_field, Some((TagU16::new(8).unwrap(), b"FIX.4.4" as &[u8])));

pub fn as_bytes(&self) -> &[u8]

Returns the underlying byte contents of self.

Examples

use fefix::tagvalue::{Config, Decoder};
use fefix::prelude::*;

const DATA: &[u8] = b"8=FIX.4.4|9=42|35=0|49=A|56=B|34=12|52=20100304-07:59:30|10=185|";

let mut decoder = Decoder::<Config>::new(Dictionary::fix44());
decoder.config_mut().set_separator(b'|');

let message = decoder.decode(DATA).unwrap();
assert_eq!(message.as_bytes(), DATA);

pub fn len(&self) -> usize

Returns the number of FIX tags contained in self.

Examples

use fefix::tagvalue::{Config, Decoder};
use fefix::prelude::*;

const DATA: &[u8] = b"8=FIX.4.4|9=42|35=0|49=A|56=B|34=12|52=20100304-07:59:30|10=185|";

let mut decoder = Decoder::<Config>::new(Dictionary::fix44());
decoder.config_mut().set_separator(b'|');

let message = decoder.decode(DATA).unwrap();
assert_eq!(message.len(), message.fields().count());

Trait Implementations

impl<'a, T: Clone> Clone for Message<'a, T>

fn clone(&self) -> Message<'a, T>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<'a, T: Debug> Debug for Message<'a, T>

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

Formats the value using the given formatter.

impl<'a, F, T> FieldAccess<F> for Message<'a, T> where
    F: IsFieldDefinition,
    T: AsRef<[u8]> + Clone, 

type Group = MessageGroup<'a, T>

The type returned by FieldAccess::group() and FieldAccess::group_opt().

fn group_opt(
    &self,
    field: &F
) -> Option<Result<Self::Group, <usize as FixValue<'a>>::Error>>

Queries self for a group tagged with key which may or may not be present in self. This differs from FieldAccess::group() as missing groups result in None rather than Err.

fn fv_raw(&self, field: &F) -> Option<&[u8]>

Queries self for field and returns its raw contents.

fn group(
    &self,
    field: &F
) -> Result<Self::Group, Option<<usize as FixValue<'_>>::Error>>

Queries self for a group tagged with key. An unsuccessful query results in [Err(None)].

fn fv<'a, V>(&'a self, field: &F) -> Result<V, Option<V::Error>> where
    V: FixValue<'a>, 

Queries self for field and deserializes it.

fn fvl<'a, V>(&'a self, field: &F) -> Result<V, Option<V::Error>> where
    V: FixValue<'a>, 

Like FieldAccess::fv(), but with lossy deserialization.

fn fv_opt<'a, V>(&'a self, field: &F) -> Option<Result<V, V::Error>> where
    V: FixValue<'a>, 

Queries self for field and deserializes it. This differs from FieldAccess::fv() as missing fields result in None rather than Err.

fn fvl_opt<'a, V>(&'a self, field: &F) -> Option<Result<V, V::Error>> where
    V: FixValue<'a>, 

Like FieldAccess::fv_opt(), but with lossy deserialization.

impl<'a, T> FieldAccess<u32> for Message<'a, T> where
    T: AsRef<[u8]> + Clone, 

type Group = MessageGroup<'a, T>

The type returned by FieldAccess::group() and FieldAccess::group_opt().

fn group_opt(
    &self,
    tag: &u32
) -> Option<Result<Self::Group, <usize as FixValue<'_>>::Error>>

Queries self for a group tagged with key which may or may not be present in self. This differs from FieldAccess::group() as missing groups result in None rather than Err.

fn fv_raw(&self, tag: &u32) -> Option<&[u8]>

Queries self for field and returns its raw contents.

fn group(
    &self,
    field: &F
) -> Result<Self::Group, Option<<usize as FixValue<'_>>::Error>>

Queries self for a group tagged with key. An unsuccessful query results in [Err(None)].

fn fv<'a, V>(&'a self, field: &F) -> Result<V, Option<V::Error>> where
    V: FixValue<'a>, 

Queries self for field and deserializes it.

fn fvl<'a, V>(&'a self, field: &F) -> Result<V, Option<V::Error>> where
    V: FixValue<'a>, 

Like FieldAccess::fv(), but with lossy deserialization.

fn fv_opt<'a, V>(&'a self, field: &F) -> Option<Result<V, V::Error>> where
    V: FixValue<'a>, 

Queries self for field and deserializes it. This differs from FieldAccess::fv() as missing fields result in None rather than Err.

fn fvl_opt<'a, V>(&'a self, field: &F) -> Option<Result<V, V::Error>> where
    V: FixValue<'a>, 

Like FieldAccess::fv_opt(), but with lossy deserialization.

impl<'a, T> PartialEq<Message<'a, T>> for Message<'a, T>

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

This method tests for self and other values to be equal, and is used by ==.

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

This is supported on crate feature utils-slog only.
