Struct CommandFields 

#[non_exhaustive]
pub struct CommandFields {
    pub key: usize,
    pub command: usize,
}

Where the key and the command sit in a COMMAND-mode field schema [docs/spec/04-notifications.md §3.2].

Both positions are 1-based, matching the numbering ItemUpdate uses everywhere.

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.

key: usize

Position of the field that identifies the row.

command: usize

Position of the field that says what happened to the row — ADD, UPDATE or DELETE.
