Struct SyncContext 

pub struct SyncContext { /* private fields */ }

Context for managing sync lifecycle, cancellation, and status updates

Implementations

impl SyncContext

pub fn new() -> Arc<Self>

Creates a new sync context

pub fn set_listener(&self, listener: Arc<dyn SyncStatusListener>)

Sets the status listener for this context

pub fn cancel(&self)

Cancels the sync operation

impl SyncContext

pub fn notify_status(&self, status: SyncStatus)

Notifies the status listener if one is set (internal use only)

pub fn token(&self) -> CancellationToken

Returns a child token for passing to async tasks (internal use only)

This uses child_token() rather than clone() to enable hierarchical cancellation:

• When the parent context is cancelled, all child tokens are automatically cancelled
• This allows the sync operation to spawn multiple tasks that all respect cancellation
• Cancelling a child token does NOT cancel the parent or sibling tasks

This pattern is recommended by tokio-util for managing cancellation across task hierarchies.

pub fn listener(&self) -> Option<Arc<dyn SyncStatusListener>>

Returns a clone of the status listener (internal use only)
