Enum Transient 

#[non_exhaustive]
pub enum Transient {
    Conflict(Failure),
    Other(Failure),
}

A failure of the category Category::Transient: trying again later, unchanged, may succeed.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Conflict(Failure)

A precondition of the write did not hold, since the state it was decided on has moved on.

Other(Failure)

Any other transient failure, such as a database that can not be reached, or one that asks to be asked again later.
