Struct hotfix_encoding::field_types::CheckSum

pub struct CheckSum(pub u8);

The result of a FIX checksum calculation (0-255).

You generally shouldn’t need to use CheckSum directly unless you’re building custom low-level FIX primitives (e.g. a new decoder).

Tuple Fields

0: u8

Implementations

impl CheckSum

pub fn compute(data: &[u8]) -> Self

Returns the CheckSum of data. The result is always the sum of each byte in data wrapped at 0xFF, as per the FIX specification.

Trait Implementations

impl Clone for CheckSum

fn clone(&self) -> CheckSum

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for CheckSum

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

Formats the value using the given formatter.

impl<'a> FieldType<'a> for CheckSum

type Error = &'static str

The error type that can arise during deserialization.

type SerializeSettings = ()

A type with values that customize the serialization algorithm, e.g. padding information.

fn serialize_with<B>(&self, buffer: &mut B, _settings: ()) -> usizewhere B: Buffer,

Writes self to buffer using custom serialization settings.

fn deserialize(data: &'a [u8]) -> Result<Self, Self::Error>

Parses and deserializes from data.

fn deserialize_lossy(data: &'a [u8]) -> Result<Self, Self::Error>

Like FieldType::deserialize, but it’s allowed to skip some amount of input checking. Invalid inputs might not trigger errors and instead be deserialized as random values.

fn serialize<B>(&self, buffer: &mut B) -> usizewhere B: Buffer,

Writes self to buffer using default settings.

fn to_bytes(&self) -> Vec<u8>

Serializes self to a Vec of bytes, allocated on the fly.

fn to_string(&self) -> String

Allocates a String representation of self, using FieldType::to_bytes.

impl PartialEq for CheckSum

fn eq(&self, other: &CheckSum) -> 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.
