Enum RejectionReason 

#[non_exhaustive]
pub enum RejectionReason {
    EnoughSpaceIsNotAvailableAndKeyFailedToEvictOthers,
    KeyWeightIsGreaterThanCacheWeight,
    KeyDoesNotExist,
    KeyAlreadyExists,
}

RejectionReason defines the reason for a command getting rejected. Available since v0.0.3.

EnoughSpaceIsNotAvailableAndKeyFailedToEvictOthers: If the cache weight is full, and the incoming key can not evict others.

KeyWeightIsGreaterThanCacheWeight: The weight of the incoming key is greater than the total cache weight.

KeyDoesNotExist: Key does not exist during delete operation.

KeyAlreadyExists: Key already exists during put operation.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.
