Trait RepositoryTransaction 

pub trait RepositoryTransaction {
    type Error;

    // Required methods
    fn save(self: Box<Self>) -> BoxFuture<'static, Result<(), Self::Error>>;
    fn cancel(self: Box<Self>) -> BoxFuture<'static, Result<(), Self::Error>>;
}

A RepositoryTransaction can be saved or cancelled, after a series of operations.

Required Associated Types

type Error

The error type used by the Self::save and Self::cancel functions

Required Methods

fn save(self: Box<Self>) -> BoxFuture<'static, Result<(), Self::Error>>

Commit the transaction

Errors

Returns an error if the underlying storage backend failed to commit the transaction.

fn cancel(self: Box<Self>) -> BoxFuture<'static, Result<(), Self::Error>>

Rollback the transaction

Errors

Returns an error if the underlying storage backend failed to rollback the transaction.

Dyn Compatibility

This trait is dyn compatible.

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