Implementations

source

impl<T> Context<T>

source

pub fn subsystem(&self) -> &T

Returns a reference to the context’s subsystem instance

source

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

source

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

Sets a value in the context’s storage

Arguments

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

source

pub fn clear(&self, name: &str)

Clears a single key/value from storage

Arguments

key - Key to clear (along with corresponding value)

source

pub fn clear_all(&self)
