Function write_frame 

Source 
pub fn write_frame(
    writer: &mut impl Write,
    message: Message,
    max_frame_bytes: u32,
) -> Result<(), ProtocolError>
Expand description

Serialise message as a length-delimited JSON frame to writer.

max_frame_bytes is the per-frame cap negotiated for this connection. Until the handshake completes, callers pass MAX_FRAME_BYTES as the default; afterwards the supervisor passes the Message::ConfigureFrameLimit value installed on the connection.

ยงErrors

Returns ProtocolError::FrameTooLarge if the serialised body would exceed max_frame_bytes, or the underlying ProtocolError::Io / ProtocolError::Json for codec failures.
