pub struct CellContext { /* private fields */ }Expand description
Execution context for a running cell.
Provides resource management and cleanup hooks for cells that need to manage background tasks or external resources.
Implementations§
Source§impl CellContext
impl CellContext
Sourcepub fn is_aborted(&self) -> bool
pub fn is_aborted(&self) -> bool
Check if execution has been aborted.
Sourcepub fn on_cleanup(&mut self, handler: impl FnOnce() + Send + 'static)
pub fn on_cleanup(&mut self, handler: impl FnOnce() + Send + 'static)
Register a cleanup handler to be called when the cell is unloaded.
Cleanup handlers are called in reverse order of registration.
