Enum CacheSize

Source
#[non_exhaustive]
pub enum CacheSize { Unbounded, Disabled, }
Expand description

Set cache size for a connection

Variants (Non-exhaustive)§

This enum is marked as 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.
§

Unbounded

Caches all queries if possible

§

Disabled

Disable statement cache
