Enum tinylfu_cached::cache::command::CommandStatus

pub enum CommandStatus {
    Pending,
    Accepted,
    Rejected(RejectionReason),
    ShuttingDown,
}

CommandStatus defines the status of each command.

Pending: the initial status of the command, before a command is acted upon.

Accepted: the command is successfully completed.

Rejected: the command is rejected. RejectionReason is now available with the Rejected status (v0.0.2)

• Put may be rejected for various reasons. One reason is: the weight of the the incoming key/value pair is more than the total cache weight.
• Delete will be rejected if the key to be deleted is not preset in the cache.

ShuttingDown: all the commands that could sneak in while the cache is being shutdown will be returned with ShuttingDown status.
