Enum WriteSource 

pub enum WriteSource {
    Derived {
        exercise_copies: Vec<ExerciseCopy>,
        generated_blocks: HashSet<Uuid>,
    },
    Revert {
        call_id: Uuid,
        writes: Vec<StagedEntity>,
        read_states: HashMap<EntityKey, Option<EntitySnapshot>>,
    },
}

Where a write call’s entity writes come from.

Variants

Derived

Found by comparing the staged state with the state after the call.

Fields

exercise_copies: Vec<ExerciseCopy>

generated_blocks: HashSet<Uuid>

The client ids of blocks the server wrote rather than the agent, besides the exercise copies; see validate_changed_blocks.

Revert

A revert of the call call_id. Skips validation: it restores content that was valid when it was written.

Fields

call_id: Uuid

writes: Vec<StagedEntity>

read_states: HashMap<EntityKey, Option<EntitySnapshot>>

The state each written entity had when the caller read it: staged where the changeset has it, live otherwise.
