Struct PutOrUpdateRequest 

Source 
pub struct PutOrUpdateRequest<Key, Value>
where
    Key: Hash + Eq + Send + Sync + Clone,
    Value: Send + Sync,
{ /* private fields */ }
Expand description

PutOrUpdateRequest encapsulates the fields that are required for a put or an update operation.

It is a parameter to put_or_update method of crate::cache::cached::CacheD.

It allows put operation with value, weight and time_to_live and also provides flexibility in updating just the value or the weight or the time_to_live or all of these for an existing key.

It also allows removing the time_to_live against an existing key. Either of time_to_live or remove_time_to_live can be provided.

If PutOrUpdateRequest results in a put operation, the flag remove_time_to_live will have no significance.
