[−][src]Struct eff::context::Context
The untyped context of an effectful computation
Methods
impl Context[src]
pub fn current() -> Self[src]
Create a context within the current thread
pub fn contains(&self) -> bool[src]
Returns true if the task-local storage contains any value
Returns false if it does not.
pub fn take<T>(&self) -> Option<T>[src]
Takes the value out of the task-local storage
pub fn set<T>(&self, v: T)[src]
Assign a value to the task-local storage
pub fn typed<E: Effect>(&self) -> TypedContext<E>[src]
Create a typed context which shares the same task-local storage
