Enum Access 

#[non_exhaustive]
pub enum Access {
    ReadWrite,
    ReadOnly,
}

A transaction’s access mode.

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.

ReadWrite

The default everywhere; stating it is allowed and explicit.

ReadOnly

PostgreSQL BEGIN … READ ONLY, MySQL START TRANSACTION READ ONLY. Refused on SQLite, which has no per-transaction read-only mode.
