Struct artemis_normalized_cache::QueryStore

pub struct QueryStore { /* fields omitted */ }

A reference to the store used to run custom query updates

Implementations

impl QueryStore

pub fn update_query<'a, Q: GraphQLQuery, F>(
    &'a self,
    _query: Q,
    variables: Q::Variables,
    updater_fn: F,
    dependencies: &mut HashSet<String>
) where
    F: FnOnce(Option<Q::ResponseData>) -> Option<Q::ResponseData> + 'a, 

Run a custom update function against the cache.

Parameters

• _query - The GraphQLQuery object for the query you want to update.
• variables - The Variables for the query you want to update. It will only update cached results for that set of variables.
• updater_fn - The custom updater function. This takes in an Option<ResponseData> that represents the current state and should return an Option<ResponseData> that represents the new state. None means deleting the entry in this context. The current state is cloned, so feel free to modify and return it.
• dependencies - This is passed into the update closure and should simply be passed through.
