Enum StdioError 

pub enum StdioError {
    Transport,
    ReplyTooLarge {
        limit: MaxFrameSize,
        len: usize,
    },
}

Why the stdio transport could not carry a frame.

Deliberately not crate::application::jsonrpc::SourceError or crate::application::session::SinkError. Those are the ports, and they carry no detail on purpose: the application layer is protocol-neutral and must not learn that a broken pipe and an oversized reply are different failures. This is the transport’s own account, and it is what a caller driving StdioSource or StdioSink directly actually learns.

Variants

Transport

The peer’s stream refused a read or a write.

Carries no io::Error on purpose, for the reason the ports do not: a caller in a position to do something about which failure it was inspects its own transport, and one that is not has nothing useful to do with the difference.

ReplyTooLarge

A reply was larger than the transport is configured to write.

Terminal, and not a truncated write. The document does not fit a frame, so there is no frame to write, and writing the bytes anyway would put a line on the wire that the peer’s decoder must then reject as malformed — a protocol error caused by our own answer, reported as a protocol error from the peer’s side, with nothing in this process to connect the two.

Fields

limit: MaxFrameSize

The ceiling the caller configured.

len: usize

The length of the reply that was refused, in bytes.
