[Discussion] Consistency (Strong vs Eventual): give a better name

[cottinisimone]

This discussion is related to this PR

@emturner proposed this:

/// Governs the relationship of an event to a resulting projection.
pub enum ParentEventRelationship {
   ///  This projector must succeed, for the parent event to be persisted.
   Blocking,
   /// This projector is allowed to fail, and doesn't block persisting the parent event.
   Fallible
}

It seems to me that ParentEventRelationship is a bit a too long name. What do you think about renaming it in Persistence? This seems to me that is moreover more consistent with PgStore::persist function

/// Specify the persistence for that projector
pub enum Persistence {
    ///  This projector must succeed, for the event to be persisted.
    Mandatory,
    /// This projector is allowed to fail, and doesn't block persisting the event.
    Fallible,
}

Or ProjectorPersistence too. Anyway no strong opinions on this topic

@cottinisimone I agree that the original suggestion is a bit too long!

Fwiw, I like your suggestion of ProjectorPersistence, with Mandatory & Fallible
