Struct SaveChangesContext 

pub struct SaveChangesContext { /* private fields */ }

Read-only snapshot of the save operation, passed to interceptors.

Built from the actual pending entries across all DbSets (the real save data source), so interceptors see a snapshot consistent with what save_changes() will commit. This is an owned snapshot so interceptors cannot mutate the pending changes, and the borrow does not block subsequent mutating operations on DbContext.

Implementations

impl SaveChangesContext

pub fn from_views(entries: Vec<EntityEntryView>) -> Self

Creates a context from the pending entries aggregated across all DbSets. Counts are derived from each entry’s state.

pub fn entries(&self) -> &[EntityEntryView]

Returns all pending entity entries at the time of interception.

pub fn added_count(&self) -> usize

Number of entities that will be / were added.

pub fn modified_count(&self) -> usize

Number of entities that will be / were modified.

pub fn deleted_count(&self) -> usize

Number of entities that will be / were deleted.

pub fn total_count(&self) -> usize

Total number of tracked entries.
