Struct GlobalContext 

Source
pub struct GlobalContext { /* private fields */ }
Expand description

Global context manager for shared state

This provides a global context that can be shared across threads in environments that support it (not available in WASM).

Implementations§

Source

pub fn get<T: 'static + Send + Sync + Clone>(&self) -> Option<T>

Get a typed value from the global context

Source

pub fn remove<T: 'static + Send + Sync>(&self) -> bool
