Struct FrameCodec 

pub struct FrameCodec { /* private fields */ }

Frame codec for encoding/decoding JSON-RPC messages

Uses Content-Length header framing similar to LSP/MCP.

Implementations

impl FrameCodec

pub fn new() -> Self

Create a new frame codec with default settings

pub fn with_max_size(max_message_size: usize) -> Self

Create a frame codec with a custom max message size

pub fn encode(&self, message: &JsonRpcMessage) -> Result<Vec<u8>>

Encode a message into a framed byte vector

Format: Content-Length: <length>\r\n\r\n<json>

pub fn encode_to_writer<W: Write>( &self, writer: &mut W, message: &JsonRpcMessage, ) -> Result<()>

Encode a message and write to a writer

pub fn decode_from_buffer<'a>( &self, buffer: &'a [u8], ) -> Result<(&'a [u8], Option<JsonRpcMessage>)>

Decode a message from a complete buffer

Returns the remaining unconsumed bytes and the parsed message. Returns Ok((remaining, None)) if more data is needed.

pub fn max_message_size(&self) -> usize

Get the maximum message size
