Struct MailboxStats 

#[non_exhaustive]
pub struct MailboxStats {
    pub held_frames: usize,
    pub held_bytes: usize,
    pub peak_frames: usize,
    pub peak_bytes: usize,
    pub backpressure_waits: u64,
    pub refused_frames: u64,
    pub ignored_frames: u64,
    pub undelivered_errors: u64,
}

Counters describing one stream’s mailbox, readable at any time from the stream that owns it.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

held_frames: usize

Items held now.

held_bytes: usize

Payload bytes held now.

peak_frames: usize

Most items ever held at once.

peak_bytes: usize

Most payload bytes ever held at once.

backpressure_waits: u64

Times the reader found the mailbox full and stopped reading the socket until the consumer made room.

refused_frames: u64

Items refused because they could never fit the mailbox.

ignored_frames: u64

Frames of a kind this stream does not carry, read and counted rather than surfaced, so a stray frame cannot stop the frames behind it.

undelivered_errors: u64

Reader errors (a server-ended subscription, a read or decode failure) that no consumer was left to receive.
