IsolationLevel

uni_db::api::transaction

Enum IsolationLevel 

Source 
#[non_exhaustive]
pub enum IsolationLevel {
    Serialized,
}
Expand description

Transaction isolation level.

Uses commit-time serialization: tx() allocates a private L0 buffer without acquiring the writer lock; the writer lock is only acquired at commit time for WAL + merge.

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.
§

Serialized

Serialized isolation with begin-time writer lock.
