Struct TokioCommandRunner 

pub struct TokioCommandRunner;

Default CommandRunner that uses tokio::process::Command.

On Unix the child is launched in its own process group via setpgid(0, 0). pg_dump --jobs N forks worker processes that share the leader’s pgid, so on cancellation we deliver SIGTERM to the whole group (kill(-pgid, SIGTERM)) and escalate to SIGKILL after a short grace window. Without this, killing only the leader leaves the workers re-parented to PID 1 and still pumping bytes from the source. kill_on_drop is also set so a cancelled future never leaks even if the explicit kill path takes the slow road.

Trait Implementations

impl Clone for TokioCommandRunner

fn clone(&self) -> TokioCommandRunner

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl CommandRunner for TokioCommandRunner

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.

impl Debug for TokioCommandRunner

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for TokioCommandRunner

fn default() -> TokioCommandRunner

Returns the “default value” for a type.
