Struct RequestDecoder

pub struct RequestDecoder { /* private fields */ }

A decoder for HTTP requests that handles both headers and payload

The decoder operates in two phases:

1. Header parsing: Decodes the request headers using [HeaderDecoder]
2. Payload parsing: If present, decodes the request body using [PayloadDecoder]

State Machine

The decoder maintains its state through the payload_decoder field:

• None: Currently parsing headers
• Some(PayloadDecoder): Currently parsing payload

Implementations

impl RequestDecoder

pub fn new() -> Self

Creates a new RequestDecoder instance

Trait Implementations

impl Decoder for RequestDecoder

fn decode( &mut self, src: &mut BytesMut, ) -> Result<Option<Self::Item>, Self::Error>

Attempts to decode an HTTP request from the provided buffer

Returns

• Ok(Some(Message::Header(_))): Successfully decoded request headers
• Ok(Some(Message::Payload(_))): Successfully decoded a payload chunk
• Ok(None): Need more data to proceed
• Err(_): Encountered a parsing error

type Item = Message<(RequestHeader, PayloadSize)>

The type of decoded frames.

type Error = ParseError

The type of unrecoverable frame decoding errors.

fn decode_eof( &mut self, buf: &mut BytesMut, ) -> Result<Option<Self::Item>, Self::Error>

A default method available to be called when there are no more bytes available to be read from the underlying I/O.

fn framed<T>(self, io: T) -> Framed<T, Self>

where T: AsyncRead + AsyncWrite, Self: Sized,

Provides a Stream and Sink interface for reading and writing to this Io object, using Decode and Encode to read and write the raw data.

impl Default for RequestDecoder

fn default() -> Self

Returns the “default value” for a type.
