Trait abstracting an external command execution. The default implementation is TokioCommandRunner.

Implementations must honour cancel: if the token fires while the child is running, the child should be killed and the call should return MigrationError::Cancelled. Without this, a multi-hour pg_dump would ignore Ctrl+C until completion.

Required Methods

fn run<'life0, 'life1, 'life2, 'life3, 'life4, 'async_trait>( &'life0 self, program: &'life1 str, args: &'life2 [String], env: &'life3 [(String, String)], cancel: &'life4 CancellationToken, ) -> Pin<Box<dyn Future<Output = Result<()>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait, 'life2: 'async_trait, 'life3: 'async_trait, 'life4: 'async_trait,

Run program with args and the given environment additions. Should fail if the process exits with a non-zero status, or return MigrationError::Cancelled if cancel fires before the child exits.
