Response

The sequence of channel responses that answers the channel, what ends it, and what a finish with nothing before it means.

[0]             ok
[1][message …]  an error, UTF-8
[2]             read only: the volume is read only
  • The sequence. Exactly one channel response, ok, read only, or an error, followed by the channel response finish.
  • The message. The bytes after the error byte are UTF-8, not JSON.
  • Read only. The byte 2 states that the volume’s mode is read_only: the change is refused, and the volume is as it was.
  • A finish with nothing. A channel response finish that no channel response precedes states that the server could not serve the ask. The client decides whether to ask again.

The channel response is defined by diverge-sdk-rs/src/provider/endpoints/volumes/fuse_serve/server/channel_response/rename/frame.rs:

//! What a server's channel response frame carries on a rename
//! channel of a FUSE serve.

/// Ok, read only, or why not. See [`fuse::rename::response::Frame`](crate::shared::containers::fuse::rename::response::Frame).
///
/// An alias rather than a re-export because this module is real: the
/// path says this scope's answer lives here, and it does, rather than
/// naming somewhere else and hoping a reader follows. What the alias
/// points at is right there in the signature.
