Struct Decoder 

pub struct Decoder<'a> { /* private fields */ }

Zero-copy FIX message decoder.

The decoder parses FIX messages from a byte buffer, extracting fields as references to the original data without copying.

Implementations

impl<'a> Decoder<'a>

pub const fn new(input: &'a [u8]) -> Decoder<'a>

Creates a new decoder for the given input buffer.

Arguments

• input - The FIX message bytes to decode

pub const fn with_checksum_validation(self, validate: bool) -> Decoder<'a>

Sets whether to validate checksums during decoding.

Arguments

• validate - Whether to validate checksums

pub fn decode(&mut self) -> Result<RawMessage<'a>, DecodeError>

Decodes a complete FIX message from the buffer.

Returns

A RawMessage containing zero-copy references to the parsed fields.

Errors

Returns DecodeError if the message is malformed or incomplete.

pub fn next_field(&mut self) -> Option<FieldRef<'a>>

Parses the next field from the buffer.

Returns

The next field, or None if the buffer is exhausted.

pub const fn offset(&self) -> usize

Returns the current offset in the buffer.

pub fn remaining(&self) -> &'a [u8]

Returns the remaining bytes in the buffer.

pub fn is_empty(&self) -> bool

Returns true if the buffer has been fully consumed.

pub fn reset(&mut self)

Resets the decoder to the beginning of the buffer.

impl<'a> Debug for Decoder<'a>

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

Formats the value using the given formatter.
