Struct RestartSupervisor 

pub struct RestartSupervisor { /* private fields */ }

Implementations

impl RestartSupervisor

pub fn new(current: Child) -> Self

pub fn current_id(&self) -> u32

pub fn current_is_running(&mut self) -> Result<bool>

pub fn supersede(&mut self, revision: u64) -> Result<()>

Marks all earlier build/startup work stale without interrupting the running application.

pub fn build(&mut self, revision: u64, command: &mut Command) -> Result<()>

Command must build into an isolated output path; never overwrite the running executable. Configure stdout/stderr as files or inherited streams, not unconsumed pipes.

pub fn poll_build(&mut self) -> Result<Option<BuiltRevision>>

None means the build is still running. Failure and supersession never retire the old process.

pub fn launch( &mut self, ticket: BuiltRevision, command: &mut Command, state: &RestartState, timeout: Duration, ) -> Result<()>

The supplied command must run the artifact produced by the ticket’s build. State is captured after building, so edits made while the compiler runs are retained.

pub fn poll_replacement(&mut self) -> Result<ReplacementStatus>

pub fn commit(&mut self) -> Result<()>

Retires the old process only after an explicit successful startup acknowledgement.

Trait Implementations

impl Drop for RestartSupervisor

fn drop(&mut self)

Executes the destructor for this type.

fn pin_drop(self: Pin<&mut Self>)

🔬This is a nightly-only experimental API. (pin_ergonomics)

Execute the destructor for this type, but different to Drop::drop, it requires self to be pinned.
