Struct hotfix_encoding::decoder::Message

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

A FIX message returned by Decoder or [DecoderStreaming].

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 hotfix_encoding::config::{Config, GetConfig};
use hotfix_encoding::decoder::{Decoder};
use hotfix_dictionary::{Dictionary, TagU32};

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::new(Dictionary::fix44());
decoder.config_mut().separator = b'|';

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

assert_eq!(first_field, Some((TagU32::new(8).unwrap(), b"FIX.4.4" as &[u8])));

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

Returns the underlying byte contents of self.

Examples

use hotfix_encoding::config::{Config, GetConfig};
use hotfix_encoding::decoder::{Decoder};
use hotfix_dictionary::{Dictionary, TagU32};

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::new(Dictionary::fix44());
decoder.config_mut().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 hotfix_encoding::config::{Config, GetConfig};
use hotfix_encoding::decoder::{Decoder};
use hotfix_dictionary::{Dictionary, TagU32};

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::new(Dictionary::fix44());
decoder.config_mut().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> FieldMap<&F> for Message<'a, T>where F: IsFieldDefinition, T: AsRef<[u8]> + Clone,

type Group = MessageGroup<'a, T>

The type returned by FieldMap::group and FieldMap::group_opt.

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

Looks for a group that starts with field within self.

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

Looks for a field within self and then returns its raw byte contents, if it exists.

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

Like FieldMap::group, but doesn’t return an Err if the group is missing.

fn get<'a, V>(&'a self, field: F) -> Result<V, FieldValueError<V::Error>>where V: FieldType<'a>,

Looks for a field within self and then decodes its raw byte contents via FieldType::deserialize, if found.

fn get_lossy<'a, V>(&'a self, field: F) -> Result<V, FieldValueError<V::Error>>where V: FieldType<'a>,

Like FieldMap::get, but with lossy deserialization.

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

Like FieldMap::get, but doesn’t return an Err if field is missing.

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

Like FieldMap::get_opt, but with lossy deserialization.

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

type Group = MessageGroup<'a, T>

The type returned by FieldMap::group and FieldMap::group_opt.

fn group( &self, tag: u32 ) -> Result<Self::Group, FieldValueError<<usize as FieldType<'_>>::Error>>

Looks for a group that starts with field within self.

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

Looks for a field within self and then returns its raw byte contents, if it exists.

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

Like FieldMap::group, but doesn’t return an Err if the group is missing.

fn get<'a, V>(&'a self, field: F) -> Result<V, FieldValueError<V::Error>>where V: FieldType<'a>,

Looks for a field within self and then decodes its raw byte contents via FieldType::deserialize, if found.

fn get_lossy<'a, V>(&'a self, field: F) -> Result<V, FieldValueError<V::Error>>where V: FieldType<'a>,

Like FieldMap::get, but with lossy deserialization.

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

Like FieldMap::get, but doesn’t return an Err if field is missing.

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

Like FieldMap::get_opt, but with lossy deserialization.

impl<'a, T> PartialEq 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 method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
