[][src]Struct kubos_service::Context

pub struct Context<T> {
    pub subsystem: T,
    pub storage: Arc<RwLock<HashMap<String, String>>>,

Context struct used by a service to provide Juniper context, subsystem access and persistent storage.


subsystem: T
storage: Arc<RwLock<HashMap<String, String>>>


impl<T> Context<T>[src]

pub fn subsystem(&self) -> &T[src]

Returns a reference to the context's subsystem instance

pub fn get(&self, name: &str) -> String[src]

Attempts to get a value from the context's storage


name - Key to search for in storage

pub fn set(&self, key: &str, value: &str)[src]

Sets a value in the context's storage


key - Key to store value under value - Value to store

pub fn clear(&self, name: &str)[src]

Clears a single key/value from storage


key - Key to clear (along with corresponding value)

pub fn clear_all(&self)[src]

Clears all key/value pairs from storage
