Trait ModelTracker
pub trait ModelTracker {
// Required methods
fn attach_peer(&self, peer: ModelPeer<'_>);
fn track_row_count_changes(&self);
fn track_row_data_changes(&self, row: usize);
}Expand description
This trait defines the interface that users of a model can use to track changes
to a model. It is supplied via Model::model_tracker and implementation usually
return a reference to its field of ModelNotify.
Required Methods§
fn attach_peer(&self, peer: ModelPeer<'_>)
fn attach_peer(&self, peer: ModelPeer<'_>)
Attach one peer. The peer will be notified when the model changes
fn track_row_count_changes(&self)
fn track_row_count_changes(&self)
Register the model as a dependency to the current binding being evaluated, so that it will be notified when the model changes its size.
fn track_row_data_changes(&self, row: usize)
fn track_row_data_changes(&self, row: usize)
Register a row as a dependency to the current binding being evaluated, so that it will be notified when the value of that row changes.
Dyn Compatibility§
This trait is dyn compatible.
In older versions of Rust, dyn compatibility was called "object safety".
