Trait CommandTransaction 

pub trait CommandTransaction: MultiVersionCommandTransaction + QueryTransaction {
    type SingleVersionCommand<'a>: SingleVersionCommandTransaction

Required Associated Types

type SingleVersionCommand<'a>: SingleVersionCommandTransaction where Self: 'a

Required Methods

fn begin_single_command<'a, I>( &self, keys: I, ) -> Result<Self::SingleVersionCommand<'_>>

where I: IntoIterator<Item = &'a EncodedKey>,

fn get_changes(&self) -> &TransactionalDefChanges

Get reference to catalog changes for this transaction

Provided Methods

fn with_single_command<'a, I, F, R>(&self, keys: I, f: F) -> Result<R>

where I: IntoIterator<Item = &'a EncodedKey>, F: FnOnce(&mut Self::SingleVersionCommand<'_>) -> Result<R>,

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
