Trait ValTransaction 

pub trait ValTransaction<TXN>: InMemValTransaction {
    // Required method
    async fn apply_to_txn(&self, txn: &mut TXN) -> MetadataModelResult<()>;
}

Trait that wraps a local memory value and applies the change to the local memory value on commit or leaves the local memory value untouched on abort.

Required Methods

async fn apply_to_txn(&self, txn: &mut TXN) -> MetadataModelResult<()>

Apply the change (upsert or delete) to txn

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
