Struct PersistedInteractions 

#[non_exhaustive]
pub struct PersistedInteractions {
    pub created: Vec<Interaction>,
    pub invalidated: Vec<InteractionId>,
    pub failed: Option<InteractionError>,
}

What InteractionEngine::persist managed to write.

failed is the whole point of the type. A caller that ignores it and narrates “I have prepared the change below” is exactly the defect §15.5 forbids, so the outcome makes the failure impossible to overlook while still handing back the cards that were written.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

created: Vec<Interaction>

The cards now visible to the client, in specification order.

invalidated: Vec<InteractionId>

Cards a replacing insert invalidated, in application order.

failed: Option<InteractionError>

The first failure, when one specification could not be written.

Implementations

impl PersistedInteractions

pub fn is_complete(&self) -> bool

pub fn views(&self) -> Vec<InteractionView>

The cards, as the client-facing views a response block carries.
